PURPOSE : To provide the Procedure to be followed for sampling of all raw materials.
SCOPE : Applicable to all raw materials received in LL units.
RESPONSIBILITY: Analyst, section head, Head Quality Control, Production officer
Sampling: Sampling is the process of abstraction of a representative portion of material or a group of units from a larger quantity of material or collection of units. Sampling is done in order to test a small portion and obtain information that can be used as a basis for action on the large quantity or collection of units or for monitoring the production process. Since the logic of sampling is that of generalizing with the information obtained from a portion about the whole batch /consignment, a sample must accurately represent the batch / consignment that is being tested.
Sample: A sample consist of a small quantity/unit(s) one or more units of material/ product drawn from a lot or a batch, quantity of sample being collected at random without regards to their quality. The number of units or quantity of material, product in the sample is the sample size.
QC Sample Pack: It is a representative sample quantity received along with the consignment from the manufacturer which can be used as “sample for analysis” provided proper validation is available.
Raw Material: Any ingredient intended for use in the production of APIs. These may include starting materials, process aids, solvents, and reagents.
Active Pharmaceutical Ingredient (API): Any substance, which is therapeutically potent with pharmacological activity intended for use in the manufacture of a drug product.
