Head of Quality Assurance

Approval of the SOP.
To ensure the overall implementation of the SOP.

Procedure:

Precaution(s):

[][]Prior to use, user must ensure that equipment is calibrated.
[][]To ensure a fixed sample volume, always introduce the solutions with a clean and dry pipette into the measuring vessel.
[][]Handle the thermistor always very carefully. All abrasive materials should be kept away from it.
[][]Solutions containing proteins, such as sera, can only be measured once. Freezing causes denaturisation of the protein so that repetition of the measurement with the same sample would result in increased values. Thus, in the case of sera, only one measurement is possible for one sample.
[][]Only real osmolalities can be measured. It is not possible to prepare other standard solutions by dilution of a calibration solution since the activity coefficient of the solution changes with dilution.
[][]In this case Store the water which is used for the zero point calibration in glass bottles.
[][]If the same salt solution is measured several times, it must be mixed after thawing (stir briefly). During the thawing process ice floats to the top of the solution. As ice does not contain salt, the top layer of the solution is diluted while thawing.
[][]Calibration solutions can become more concentrated if the bottle is opened frequently. So, use KNAUER calibration solutions in glass ampoules.
[][]Prior to the measuring, a little bit water condensed in the cooling compartment should be removed with a dry cloth.

Operation:

[][]Preparing the Osmometer K-7400
[][]Switch ON the instrument at least 5 minutes before use.
[][]Press the vibrator key to check the stirrer. It will run for a second.
[][]Optionally a thermo printer can be connected to the RS232 socket. The result of each measurement will be printed automatically.
[][]After a calibration, an outprint of Calibration will be found automatically.
[][]In case of interrupted runs (caused by any error), the screen displays the corresponding error message.

Preparing a Measurement

[][]Place 0.15 ml sample or calibration solution into a clean, dry measurement vial.
[][]Put the vial all the way into the adapter. The meniscus of the liquid must be horizontal.
[][]Place the measuring head on the instrument in such a way that the vial extends into the cooling cavity.
[][]Thus the instrument is ready for calibrating or measuring.

Calibration:

[][]Prepare the instrument for a measurement of deionised water.
[][]Set the first field in the second row of the CALIBRATE screen to „0000“.
[][]Press the start key.
[][]After finishing the run on the screen is displayed 0000 mOsmol > -0.81°C<.
[][]To accept this value, press the START key again.
[][]Wait for the warming up to the stand-by temperature.
[][]Prepare the instrument for a measurement of a 300 mOsm/kg calibration solution.
[][]Activate the second calibration field and select “0300” and repeat steps
[][]For a 4 point calibration, repeat the procedure for calibration fields

Measuring Samples:

[][]Prepare the instrument for a measurement of a sample solution.
[][]Press the START key to start the measurement run.
[][]The instrument detects the freezing point depression and if the crystallisation occurred properly displays the corresponding osmolality on the main screen.
[][]The printer output is given automatically.
[][]If no crystallisation (temperature increase) takes place after the automatically start of the vibrator the measurement will be stopped with the error message “> ERROR < NO FREEZE”.
[][]If the crystallisation (temperature increase) takes place before the start of the vibrator the measurement also will be stopped with an error message> ERROR < FREEZE.
[][]Do not remove the measurement vessel from the adapter before the sample is molten. Otherwise the danger of damaging the measuring head is given. The sample melting can be accelerated by warming up with the fingers.

Cleaning procedure:

[][]Measuring vessel and thermistor should be cleaned occasionally with KNAUER cleaning solution supplied with the instrument. (Dilution: 1: 10 solution in purified water of 40±5°C)
[][]Clean and dry the measuring vessels with alcohol or acetone because remaining solvent vapours could cause false results.

Sr. Executive, QC

[][]To ensure the initial investigation of the test parameters and to organize the testing.

Manager, Quality Control

[][]To ensure that this procedure is kept up to date.
[][]To confirm that the SOP reflects the required working practices.
[][]To make decision for re-sampling.
[][]To arrange training on the SOP to all concerned personnel and to ensure implementation of the SOP after training.

Head of Quality Assurance

[][]Approval of the SOP.
[][]To take the final decision to release the batch.
[][]To ensure the overall implementation of the SOP.

Procedure:

[][]The procedure mentioned below shall be followed if a Laboratory result for raw materials sample, In-process Sample or Finished Product sample fails to meet the Specification.
[][]Analyst shall not destroy the sample preparation / solution and shall retain the prepared solutions, Standards and Sample solutions until the investigations have been concluded.
[][]Retain all Glassware, Blend & Finished Product Sample.
[][]Check the whole analysis for compliance (Self-check).
[][]Inform immediately to the Supervisor about the OOS result.
[][]Supervisor will discuss with the analyst about the test method and confirm analyst knowledge of and performance of the correct procedure.
[][]Check if a laboratory error could be the cause of OOS results and inform Manager, QC.
[][]Check and record the present conditions in Notification of out of specification (OOS) result as per Annexure-I.
[][]Follow the Flow Chart (Annexure-II) for OOS Investigation
[][]The QC Manager should assess the data promptly to ascertain if the results may be attributed to laboratory error, or whether the results could indicate problems in the manufacturing process.

[][]It is to be clarified together with the QC Manager whether there is an apparent analytical error. A formal check is to be carried out (Investigation stage 1) using Out of Specification (OOS) Results Investigation Checklist (Annexure – IV) which shall be issued by QC Manager making entry in the Out of specification investigation register (Annexure – III) and assigning sequential number as below:
e.g. OOS-001/xx
Where, OOS is the abbreviation of Out of Specification
001 is the sequential number of Out of Specification investigation
/ is separator
xx is last two digits of year 20xx

[][]At the first step, the QC Manager along with Analyst shall immediately try to find out any obvious Error (Example: Calculation error, Power outage, Equipment failure, Testing Error, Incorrect Instrument Parameters etc.)
[][]If any calculation error is found out, make correction the calculation and release the material/product; analyst shall be re-trained for the error parts.
[][]If the calculation / documentation are correct, proceed with the investigation of the stepwise analysis which may include re-examination of the actual solutions, test units, glassware used in the original measurements and preparations.
[][]The following steps should be taken as part of the investigation:
[][]Discuss the test method with the analyst; confirm analyst knowledge of and performance of the correct procedure.
[][]Examine the raw data obtained in the analysis, including chromatograms and spectra, and identify anomalous or suspect.
[][]Confirm the performance of the instruments.
[][]Determine that appropriate reference standards, solvents, reagents, and other solutions were used and that they meet quality control specifications.
[][]Evaluate the performance of the testing method to ensure that it is performing according to the standard expected based on method validation data.
[][]Document and preserve evidence of this investigation.
[][]Where a transient equipment malfunction or other problem in the dosage form (e.g. incomplete extraction) is suspected, re-inject the retained sample preparations to assign a cause for OOS results.
[][]When laboratory error is identified, determine the source of that error (root cause) generating CAPA as per the SOP for ‘Corrective and Preventive Action’  and take corrective action to ensure that it does not occur again. Recommend on Out of Specification (OOS) Results Investigation Checklist (Annexure – IV) for performing a repeat analysis on the same sample with the same analyst. If the repeat analysis result is passing, void the initial result and approve the batch based on the re-test result.
[][]If no apparent analytical error can be found, i.e. evidence of laboratory error remains unclear, investigation stage 2 should be conducted to determine what caused the unexpected results, which may include re-testing and/or re-sampling and further investigation.
[][]Before further investigations are carried out during the next step, the subsequent procedure has to be written down in the testing protocol (Annexure – IV).
Tasks in testing protocol:
“What” is to be done (retesting, re-sampling, etc.)?
“Who” will be carrying out the investigations (1st analyst, 2nd analyst, etc.)?
“How” will the investigations be carried out, which equipment, which reagents, additional analysis of reference samples (state batch and number of analysis)?
“How often” will the analysis be repeated (final criterion to prevent “analysis” into
“compliance”)?
[][]A justification for the procedure must be given by the QC manager prior to implementation of the testing protocol and the test plan must be approved.
The number of retests should be 3 times or more
[][]The investigation may involve re-testing a portion of the original sample. The sample used for the retesting should be taken from the same homogeneous material / product that was originally collected for the lot/batch, tested and yielded the OOS result. For a liquid, it may be from the original unit liquid product or composite of the liquid product; for a solid it may be an additional weighing from the same sample composite that had been prepared by the analyst.
[][]Decisions to retest should be based on the objectives of the testing and sound scientific judgment. Retesting should be performed by an analyst other than the one who performed the original test.
[][]If the result is within specification (passes), the material/product shall be re-analyzed by first analyst with the same sample and to investigate the first analyst.
[][]If investigation of first analyst found satisfactory then release the material/product
[][]If the material/product fails by the second analyst also, simultaneously analyze after re-sample with the previously approved material/product.
[][]Re-sampling should involve analyzing a specimen from the collection of a new sample from the batch. A re-sampling of the batch should be conducted if insufficient quantity of the original sample remains to perform all further testing or if the investigation shows that the original sample was not representative of the batch. This would be indicated, for example, by widely varied results obtained from several aliquots of the original composite (after determining there was no error in the performance of the analysis). Re-sampling should be performed by the same qualified, validated methods that were used for the initial sample. However, if the investigation reveals that the initial sampling method was in error, a new accurate sampling method must be developed, qualified and documented.
[][]If previously approved material/product passes within the specification and material/product under investigation meets the specification, release the material/product.
[][]In case of material if previously approved material passes within the specification and material under investigation fails to meet the specification, material shall be rejected.
[][]In case of product if previously approved product passes within the specification and product under investigation fails to meet the specification, the laboratory investigation may be extended to review the quality of the materials (raw & primary packaging) used in manufacturing of the finished product. If any problem in quality of the materials is identified which may have potential effect on the OOS scenario, the root cause will be attributed to that problem.
[][]The procedure is then to be implemented and the results be evaluated. The results are to be summarized in Annexure – VI (report level 2).
[][]Conclusion must be drawn and it must be stated which individual values will be entered in the result (on Certificate of Analysis).
[][]The error category of the initial OOS result must also be recorded.
[][]At measures, a statement must be made explaining how similar OOS results are to be avoided in future.
[][]During investigation of an OOS result, review the previous investigation reports to determine whether a similar occurrence has taken place.
[][]When the laboratory investigation does not determine that laboratory error caused the OOS result and testing result appears to be accurate, the laboratory investigation/report to be handed over to QA manager for a full-scale failure investigation as per the SOP for ‘Deviation Procedure’.
[][]In case the process error is identified during failure investigation, suitable corrective action shall be taken. Sample shall then be analyzed as per routine procedure and accordingly release, if the results are okay.
[][]Quality Assurance Manager will initiate the CAPA based on root cause found in the failure investigation. CAPA must be implemented within agreed time lime. All CAPAs must be implemented based on criticality.

[][]Use the instrument at an ambient temperature of 5°C to 35°C and RH lower than 90%.
[][]Disconnect the power supply before moving or cleaning of the instrument.

General procedure:

Polarimetry is used to measure the effect that an optically active molecule in solution has on polarized light. Specific Optical Rotation is defined as an Observed Optical Rotation, measured at a specific wavelength and temperature, corrected for the path length of the optical cell and concentration of the solution. The sample is normally presented to the Polarimeter as a solution, contained in a thermally controlled optical cell. A beam of polarised light is then passed through this cell and any rotation of this polarised light is measured via a detector

Reagent quality:

[][]If water is used in the preparation of sample solutions, it must be purified by distillation or deionization process.

Instrument equilibration:

[][]The instrument must be equilibrated before use. The polarimeter (set to required wavelength), must be switched on for a minimum of at least 30 minutes before use.

Preparation and storage of samples:

[][]Sample solutions must be prepared in accordance with the analytical method. Sample solutions must be discarded at the end of the working day, unless solution stability has been demonstrated.

Preparation for measurement:

[][]Connect the power cable and turn the Polarimeter ON.

[][]Type the Lot ID and press Enter.
[][]Input the sample weight and press Enter.
[][]Type the Sample Name again presses Enter.
[][]When the measurement completed, press Print Option to the results.
[][]Remove the polarimeter cell from the chamber.

Calculation of Specific Optical Rotation:
The specific optical rotation of a sample is calculated as follows:

A=αx100/I x c

Where,
[α] = Specific Rotation at Temperature, T°C and wavelength, λ nm
Α = Observed Rotation in degrees (°)
l = Path length in decimeters (dm)
c = Concentration of analyte (g /100 ml)

Cleaning of the instrument:

Cleaning of the cell:

[][]The cell must be cleaned after use. Thoroughly rinse the cell with the same solvent used for the sample, then rinse with purified water followed by methanol.

Cleaning of the sample compartment:

[][]The sample compartment should be cleaned immediately if anything is spilled into it in order to preserve the black matt finish and prevent corrosion or contamination.
[][]Use a soft cloth impregnated with a soapy solution to rub away any foreign material.
[][]Use a clean soft cloth dampened with water to rinse the cleaned surfaces thoroughly.
[][]Finally dry with a lint free cloth or tissue.

Calibration check with sucrose solution:

[][]Calculate the loss in weight as a percentage and record the result on the polarimeter calibration check sheet using the following calculation:

LOD=Weight loss(g)/Weight taken(g)x100

Determination of Specific Optical Rotation at 20°C:

[][]Accurately weigh about 20 g of Sucrose into three separate 100 ml volumetric flasks. Dissolve in 80 ml of water and dilute to 100 ml with water.
[][]Zero the polarimeter using purified water in the 1dm polarimeter tube.
[][]Determine the optical rotation of each solution at 20°C ± 0.5°C in the 1dm tube.
[][]Record and calculate the results obtained for each solution on the polarimeter calibration check sheet using the following calculation:

A=αx100x100/I x c x(100-%LOD)

Where,
[α] = Specific Rotation at Temperature, 20°C and wavelength, 589.3 nm
A = Observed Rotation in degrees (°)
l = Path length in decimeters (dm)
c = Concentration of analyte (g/100 ml)
