- Head – Quality Control
Procedure:
Sampling of Raw Materials:
- Raw material sampling shall be initiated after receiving the “GRN” from warehouse.
- QC personnel shall enter the material details in raw material control register as per Annexure No. 01 and allot A.R. No.
- QC personnel shall generate labels of “SAMPLED” as per Annexure No.08
- QC personnel shall generate labels of “UNDER TEST “as per Annexure No. 09 . The no. of ‘UNDER TEST’ labels shall be ‘no. of container(s) + 1’.
- If number of containers is five then six under test labels shall be taken out and one label will be numbered as 00 of 05, 00 of 05 for specimen label with sampling report as per Annexure No. and 01 of 05 for container number 01, 02 of 05 for container number 02 and so on.
- QC personnel shall go to the warehouse along with ‘Sampling Report of Raw Material’ as per Annexure No. 02 , GRN, Sampled labels and Under Test labels.
- QC personnel shall check the material as per GRN.
- QC personnel shall have to ensure that “Quarantine” labels are affixed on each unit pack by warehouse department.
- QC personnel shall enter into the sampling booth as per SOP. and Check the status label “CLEANED AREA” on sampling booth before entering into the sampling booth.
- Ensure that Differential pressure of the sampling booth is within the limits and record the observations as per Annexure No.03 .

- Ensure that temperature and Relative Humidity of the sampling booth is within the limits and record the observations as per Annexure No. 01
- Manometer of Reverse Laminar Air Flow is to be checked before starting the air flow. The manometer level should be at “zero” position. The RLAF shall be kept on at least before 15 min of start of sampling. Operate the RLAF as per SOP .
- Record the sampling start time and differential Pressure of the RLAF in sampling operational log book as per Annexure No. 03
- Sampling of non-sterile solid shall be carried out under RLAF located in sampling area of warehouse. Sampling of liquid materials shall be done in the area dedicated for liquid sampling.
- Sampling of sterile materials shall be done as per SOP .
- QC person shall use cleaned and dried Sampling devices. These sampling devices shall be wrapped in aluminum foil with status label “Cleaned and Ready for Use” as per Annexure No. 10
- QC personnel shall use sampling utensils as follows:
| Type of Raw material | Utensils | Sample collection container |
| For liquid sampling from drum / bag / container | S.S. sampling rod | Glass bottles |
| For liquid sampling from bottles. | S.S. sampling rod | Glass bottles |
| For sampling of material from solid bulk containers. | SS sampling rod / SS spatula | LDPE bag |
QC personnel shall open the containers or bags under the sampling booth individually and take out the sample as per sampling plan given .
Sampling Plan:
- Before taking the container(s) inside, ensure that the container(s) are clean. If any container is found damaged or with broken / tampered seal then the container shall be rejected and the same shall be informed to the In-charge of Warehouse department.
- Observe visually the appearance of the material for any abnormalities like discoloration, lumps, non-characteristic odour, foreign matter, physical heterogeneity etc.
- Material of only one batch number shall be sampled at a time. After sampling of each material cleaning shall be done as per SOP .
- Withdraw the sample from the no. of containers as per the table given below:
| Type of Material | No. of Containers | Type of sample |
| Inactive | √n + 1 of the total container | 1. Composite Quantity (for analysis & for retention sample) 2. From each sampled container (for identification) |
| Active | 100 % of total containers | 1. Composite Quantity (for analysis & for retention sample) 2. From each container (for identification) |
- If no. of containers of inactive materials are five or less than five then each individual container shall be sampled.
- Container number of each container shall be assigned as x/y where x is serial number of container and y is the total number of containers, e.g. 1/10 shall be assigned for first container out of 10 containers.
- Put the container number on label affixed on sample for identification. Label of ‘SAMPLE FOR IDENTIFICATION’ shall be as per Annexure No.13.
- QC personnel shall open the containers or bags under the sampling booth and withdraw quantities as per list prepared as per Annexure No.6 for active materials and Annexure No. 07 inactive materials.
- List for sample quantity of active and inactive raw material shall be prepared and reviewed by QC department and approved by QA department. Quantity to be sampled shall be as per approved list. Document No. shall be assigned to the list as QCSG01/D06-XX for active material and QCSG01/D07-XX for inactive materials, where XX is for version no. List shall be revised, if sample quantity of any material has to change or new material has to be added in the list.
- Sample shall be collected from top, middle & bottom of the layers from the drums for solid materials and for liquid/solvent, top and bottom portion of the barrel / containers. In case of any abnormalities observed, inform to QA Officer for necessary action.
- Mix the top, middle and bottom portion of solid raw material in S.S. sampling pan and transfer the required material for identification in LDPE (Low density polyethylene) polybag.
- In raw materials where microbiological testing is required, sample is to be drawn in a separate glass vial bearing the label “SAMPLE FOR MICROBIAL ANALYSIS” from every sampled container. Label of Sample for Microbial Analysis shall be as per Annexure No.12 .
- Glass vial and spatula for micro sample should be sterile.
- Raw materials of specific nature, are to be sampled with care, (where its potency, characters, stability are related with storage conditions, i.e. specific temperature, humidity, light resistant or any such requirements).
- For composite sample, withdraw appropriate quantity of sample equivalent to the required quantity from individual containers ensuring that approximately equal quantity are drawn from individual containers.
- Fill the required quantity from composite sample for “RETENTION SAMPLE” as well as for “SAMPLE FOR ANALYSIS”.
- Label the samples as ‘SAMPLE FOR ANALYSIS’ as per Annexure No.04’RETENTION SAMPLE’’ as per Annexure No.5
- Properly close the container(s) under RLAF and affix self-adhesive label of “SAMPLED” as per Annexure No.8 .
- Affix self-adhesive label of “UNDER TEST” as per Annexure No.9 on all containers of that batch.
- Record all observations in sampling report of raw material as per Annexure No.02
Cleaning of Sampling Devices:
- Sampling devices shall be washed with running purified water.
- During washing of the sampling devices, if any residue is visually seen, scrub the sampling devices with lint free cloth and wash it thoroughly with purified water.
- After removal of all residues from the sampling devices, rinse the sampling devices thoroughly with purified water and finally rinse the sampling devices with Isopropyl alcohol and dry it.
- After completion of drying, wrap the sampling devices in aluminum foil and put “CLEANED & READY FOR USE” status label as per Annexure No. 10
- Keep the sampling devices in a designated place.
- Record the cleaning activity in cleaning and usage log for sampling devices
- Bring the sampled polybags/ Glass Bottles to Quality Control Laboratory for analysis.
