Testing and Quality Assurance

Testing and Quality Assurance Our onsite laboratory continuously monitors the output of the production facility to ensure the highest quality of finished goods. We conduct extensive laboratory testing on state-of-the-art laboratory equipment including High Performance Liquid Chromatography (HPLC), Inductively Coupled Plasma Emission Spectrophotometry (ICP), Dissolution and Absorption, Microbiological Testing, and Fourier Transform Near Infrared Spectroscopy (FT-NIR). All products are meticulously examined for weight, ingredient homogeneity, color standardization and content levels. Tablets are tested for hardness, thickness, dissolution and integrity. This extensive laboratory testing ensures that NAI's customers are supplied with products that conform to the highest standards. NAI certifies that each raw material used meets or exceeds the requirements upheld by the U.S. Food and Drug Administration (FDA), the U.S. Pharmacopoeia (USP) and the Therapeutic Goods Administration of Australia (TGA). Raw materials are also tested to ensure that they are free of harmful pesticides and herbicides and have no trace of heavy metal contamination. NAI maintains a Retention Room where samples of product, Certificates of Analysis and identification of vendors and lot numbers for raw materials are stored for a minimum of five years. This enables the Company to trace the source of every element of every product.
