Residual Solvents Class IIA PT

NA.24

Residual Solvents Class IIA proficiency testing material is produced in accordance with ISO/IEC 17043:2010. The PT portfolio allows our test components to offer significant performance data to monitor and prove competency to customers, accreditation bodies or both.

Residual solvents in pharmaceuticals are defined as organic volatile chemicals that are used or produced in the manufacturing of drug substances, excipients, or dietary ingredients, or in the preparation of drug products or dietary supplement products.

Supelco^® Pharmaceutical Proficiency Testing scheme is mainly designed to meet the needs of the pharmaceutical industry.
The pharma PT samples allow laboratories to demonstrate their competence in following compendial USP methods of analysis. They can be used to assure accreditors or auditors that the lab processes are followed accordingly. Our pharmaceutical PT scheme covers products under categories such as Chemical Tests and Assays, Physical Tests and Determinations and Microbiological Tests.

Type of PT Scheme: Pharmaceuticals

All information regarding the use of Residual Solvents Class IIA proficiency testing standard can be found in the reporting packet which will be available to download at PT Portal.

Residual Solvents Class IIA, as a proficiency testing material is used to determine the amounts of residual solvents in pharmaceutical drug products.

We have a vast portfolio of environmental PT schemes with "fit-for-purpose" samples to help you meet the needs of the laboratory.

Our proficiency testing (PT) program is a benchmark to:

• provide staff with an insight into their laboratory′s performance, to verify the accuracy and reliability of their testing process
• provide a comparison of performance with that of other laboratories, nationally and internationally
• test and educate staff, provide a better understanding of the impact of incorrect results and identify areas where there may be problems
• provide an independent evaluation of laboratory performance
• demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality

General Instructions
1. Standard Preparation

• Add about 50 mL of water to a 100 mL volumetric flask and accurately transfer 1.0 mL of Residual Solvent Class IIA Standard to the flask, keeping the tip of the pipet below the water. Dilute to volume with water. This represents the Standard Solution.
• Add 5 mL of water to an appropriate headspace vial and accurately add 1.0 mL of Standard Solution, apply the stopper, cap, and mix.

2. Sample Preparation

• Add about 10 mL of water to a 25 mL volumetric flask and accurately transfer 1.0 mL of Residual Solvent Class IIA Sample to the flask, keeping the tip of the pipet below the water. Dilute to volume with water. This represents the PT Sample.
• Add 5.0 mL of water to an appropriate headspace vial and accurately add 1.0 mL of the PT Sample.

Analysis Procedure

• Perform the Gas Chromatography from USP general chapter <467> for Procedure A, or by using an in-house validated method for residual solvent analysis.
• Calculate and report the amount of each residual solvent that is found in the Residual Solvent Class IIA PT Sample.

Reported Data
The concentration of each residual solvent present in Residual Solvents Class IIA PT Sample (Data=Numeric)

Calculations

• C = concentration of individual residual solvent from Standard Solution Rst = Area of the individual peak from Standard Solution Rsa = Area of the individual peak from Sample Solution
• Class IIA PT Concentration = C*(Rsa/Rst)
