Comprehensive Analytical Chemistry Testing & Analysis
Precision chemistry testing for supplements, foods, cosmetics, and personal care products.
Analytical chemistry testing is the process of identifying, quantifying, and verifying the purity of chemical compounds in dietary supplements, cosmetics, and food products using instrumentation such as HPLC, ICP-MS, GC-MS, FTIR, and UV-Vis spectroscopy.
Qalitex Laboratories provides specialized chemistry lab testing services designed for regulatory compliance, consumer safety, and product integrity. Our ISO 17025 accredited laboratory serves dietary supplement, cosmetic, personal care, and dry food brands that require high-precision testing for both raw materials and finished goods.
Identity Testing
We test the authenticity and presence of active ingredients in your raw materials or finished products using USP, AOAC, and in-house validated methods. We use HPLC, FTIR, and UV-Vis spectroscopy to establish compound identity in powdered and encapsulated products.
Purity Testing
Evaluate the presence and quantity of unwanted compounds, excipients, or degradation products in your formulation. We use HPLC, UV-Vis, and titration techniques, tailoring test methods to your product's unique matrix.
Contamination Screening
Ensure your products are free of unintentional contaminants such as residues, cross-contamination, or degradation byproducts. All tests are conducted under ISO 17025-compliant procedures using validated techniques such as GC, HPLC, and FTIR.
Heavy Metal Testing
Comply with Prop 65 and international safety standards through precise heavy metal screening. We provide testing for arsenic, cadmium, lead, and mercury using ICP-MS for ultra-trace level detection, with batch certificate documentation for regulatory filings.
Pesticide Residue Testing
Our pesticide chemistry testing covers multi-residue panels using GC-MS and LC-MS instrumentation, tailored for herbal supplements, botanical teas, and functional foods. We follow USP <561>, EPA, and EU Annex II methods.
Quantitative Assay
We perform HPLC-based quantitative assays to confirm potency and consistency in finished goods, aligned with USP monographs or client-specified targets. Essential for label claim verification, product launches, and audit documentation.
