Analytical Capabilities

For analysis of your products, Puritan Products has vast analytical capabilities–a full service analytical laboratory staffed across all shifts with degreed chemists. Our laboratory provides testing for all incoming raw materials, in process production, and final packaging. We analyze your products to full compendial requirements or custom specifications tailored just for your process. Unless compendial methods are harmonized, we analyze parameters according to their compendial (USP, NF, EP, JP) method.

Our chemists also perform pilot production for new products and assist in the scale up to production size quantities. We retain all chemical products for the shelf life of the material. We offer stability testing on our cGMP products. We maintain our instrumentation through calibration, preventive maintenance, and qualification programs.
