Analytical testing

Product & raw material quality control testing

At ALS, our pharmaceutical business provides a wide range of services to the pharmaceutical and healthcare industries. Committed to exceeding client expectations we are able to provide high quality solutions across a range of products, including human and veterinary products, intermediates and raw materials ultimately for release to market or into manufacturing.

With a comprehensive range of tests, qualified analytical equipment and experienced and skilled staff, clients can have confidence in the integrity and quality of test results. Our independent GMP compliant laboratories are inspected by local healthcare regulators with many also being US-FDA inspected. Compendia analysis is supported by a broad range of chemical techniques and analytical equipment, some typical examples detailed further below.

Extensive range of analytical methods

Batch / lot release testing

Good Manufacturing Practice (GMP) for Medicinal Products requires batch release against the approved product specification. Our analytical laboratories utilise broad analytical technologies to provide responsive release testing using pharmacopoeia or client specific methods, confirming that products meet their specification. Routinely handling a diverse range of sample matrices leaves ALS well positioned to meet the needs of our clients' ever expanding product portfolios and diverse product ranges.

ALS routinely handle:

 

Raw material testing

ALS support a comprehensive range of compendia testing for raw materials, purified water, chemicals, excipients and intermediates against a range of standards including ACS, BP, EP, JP, USP and FCC. Our raw material testing helps to assure manufacturers in their plight to release materials for use in the manufacture of healthcare products.

 

Pharmacopoeia, standards & compendia methodologies include:

ALS naturally supports verification of compendia methods. The verification process for compendia test procedures is the assessment of whether the procedure can be used for its intended purpose, under the actual conditions for raw materials. Requirements are driven by both GMP legislation and USP <1226> - ALS works collaboratively with clients to form appropriate, risk-based approaches to verification where considered a requirement.
