Creative BioMart Chromatography provides impurities analysis services during the manufacturing process of pharmaceuticals and biopharmaceuticals. Whether the impurities in drugs are fully and accurately controlled will directly affect the quality control and safety of listed drugs. Impurities can take many forms, from solids to volatiles and everything in between, include organic impurities, inorganic impurities and residual solvents, which are found in starting materials, intermediates, APIs, and by-products. In addition, we also offer pharmaceutical impurity isolation service. By preparing chromatography and other techniques, the impurities can be quickly separated, and then the qualitative, quantitative and safety studies can be carried out. Our impurities analysis is carefully following the ICH guidelines to apply a range of highly specific and sensitive techniques, and will also be customized from batch to batch variation (Fig. 1). Our solutions include but are not limited to SEC, LC-MS, LC-MS/MS, UPLC, HPLC, HPTLC, GC, GC-MS, UV/Vis spectrum, ICP-OES, ICP-MS, etc.
