Analyst Qualification (Certification) In Quality Control Laboratory

1
700

This procedure is applicable for the New employee (experienced or fresher), existing analyst who is changed from one section to another section e.g. Raw material to Finished product or  enlargement of responsibility, to ensure the capability of the analyst to perform analysis accurately and to demonstrate the analyst’s ability to perform specific methods as a result of investigation in QC laboratory.

 

RESPONSIBILITIES:

Analyst: To perform the analysis for the qualification as per approved procedures and go through all the necessary trainings.

Quality Control Section In charge: Responsible for the certification of Analyst and verification of results and comparison with acceptance criteria.

Quality Control Head: Responsible for the compliance to this SOP and to ensure the competence of analyst who operate specific equipment, perform tests and calibrations.

DEFINITION : 

Certification of analyst: This procedure applies to all analyst in Quality control laboratory in order to ensure that analyst performing the tests are adequately trained to produce reliable and accurate results within the specified acceptable limits.

 

PROCEDURE :

Analyst certification shall involve determining the competency on following :

  • Understanding of the MOA of the test and analysis performed by the analyst.
  • Knowledge about the instruments used by analyst and ability to use them.
  • Performing analysis according to approved MOA’s and STP’s.
  • Evaluation of the analytical results and reporting.
  • Before analyst certification, Section In charge / Nominee shall ensure that all necessary training has been imparted to analyst.
  • Certification of analyst is not applicable for the operation of physical parameter measuring devices. Training is essential to operate the below equipment’s and measuring devices but not limited to: Disintegration apparatus, Hardness tester, Tap density tester, Sieve analysis, Refractometer, Melting point apparatus, Analytical balance, Viscometer, Laboratory Oven, Fiability apparatus, Muffle furnace, Scale etc.
  • Certification of analyst is mandatory for the operation of instrument like HPLC and GC.
  • Others instrument operation will be dealt according to the below matrix.

  • Recently fresh approved raw material or finished product or packing material shall be given to the analyst to perform testing .The samples are to be coded accordingly.
  • These samples packed in a manner which can prevent exposure to moisture, light and heat.
  • While performing the analysis the analyst must trained to follow the general laboratory practices and general safety requirements.
  • The coded sample are to be analysed in triplicate except dissolution and the analysis shall be completed within 10 working days from the receipt date.
  • Evaluate the capability of the analyst in terms of its precision to perform the tests and Laboratory practices followed by the analyst.
  • The Quality control Section In charge shall verify the results and compare with acceptance criteria
  • The analyst shall be considered qualified if the results obtained by him / her within the specification limit and within acceptable limit (as mentioned below) for certification of analyst.

 

ACCEPTANCE CRITERIA:

  • Assay of Finished product and Raw material : Mean difference should not be more than ± 3 % and RSD of three values should not be more than 1.0 %.
  • Dissolution: Mean difference should not differ by 5 % from original value and % RSD should not be more than 10.0 %.
  • Water content by KF apparatus: RSD of three values should not be more than 1.0 %.
  • Loss on drying : RSD of three values should not be more than 1.0 %.
  • Residual solvents: Mean difference should not be more than 7.5% and RSD of three values should not be more than 10.0 %.
  • Specific optical rotation : Mean difference should not be ± 3 % and RSD of three values should not be more than 10.0 %.
  • FTIR : Results should be comparable with the IR spectrum obtained with reference Standard.
  • Melting point : Results should meet the specification.
  • Grammage of aluminium foil : Results should meet the specification.
  • Related substances in Finished product and Raw material: Any individual impurity:
  1. ±  25 % from the original reported value (if the value is between 0.1 – 0.2 %).
  2. ± 15 %  from the original reported value (if the value is above  0.2 %).
  3. (Values below 0.1 % shall not be considered)
  4. Total Impurities; ± 25 % from the original reported value.
  • If the results found out of acceptance criteria, Section In Charge or his nominee shall conduct investigation through deviation for the cause and if it is due to analytical error, then the analyst shall be retrained for the respective SOP’s /Procedure and shall be again qualified.
  • The analyst is to be considered as certified, if the analytical results reported by the analyst during the evaluation study meet the established acceptance criteria.
