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.
