4.0 Procedure:
4.1Primary Standard:
4.1.1 These are materials which, after drying (or as required) under the specified conditions are recommended for use as a primary standard in standardization of volumetric solution. Or a reference substance as a primary standard that has the appropriate quality within a specified context & is accepted without requiring comparison to another substance.
4.1.2 QC Officer/Executive shall check out the primary standards required for calibration, volumetric solution standardization, and other analysis requirements.
4.1.3 QC Officer/Executive shall provide a list to the section head for procurement of primary standards.
4.1.4 Section head shall be prepared indent for primary standards as per requirement with name.

4.1.4 Mentioned the Grade, manufacturer, and quantity on indent to the procurement of primary standards.
4.1.6 Analytical reagent grade (certified) materials of commerce must be used.
4.1.7 After receiving these chemicals QC Officer/Executive shall ensure that it is labeled properly, indicating the name of the chemicals and purity with their grade.
4.1.8 Check the container seal for its integrity, if any damage or leakage is found, the same shall be sent back. If the container is found OK use the same as a primary standard.
4.1.9 Primary standards shall be Stored at the temperature mentioned on the label of the container.
4.1.10 The date of opening shall be mentioned on the container when the bottle is opened, use before the date must be assigned 3 years for solids, 2 years for liquid, and 6 months for hygroscopic materials.
4.1.11 COA of Respective primary standards shall be downloaded/received from its manufacturers, websites, or vendors.
4.1.12 Enter the details of all primary standards with unique ID No. in Annexure-l of this SOP as per the below pattern.

PS: denotes to Primary Standard,
XXX: denotes Unique ID No. for particular primary standards.

4.13 Containers of the primary standard shall be labeled with ID no. as per the below pattern.

PS: denotes to Primary Standard,
XXX: denotes to Unique ID No. for particular primary standards,
ZZ: denotes to Alternate No. for the next container of the same primary standard.

Example: PS-001-01 for the First container of the primary standard and PS-001-02 for the Second container of the same primary standard and so on.

4.1.14 Maintain the primary standards consumption record as per Annexure-ll of this SOP.
4.1.15 Dispose of the expired primary standard as per SOP No. QC/CHE/021 for Disposal of Residual sample/Leftover material

4.2 Precaution:
4.2.1 Take only the required quantity of the primary standards from the respective containers and do not add the remaining Quantity of primary standards in the original container.
