The laboratory currently provides laboratory services in the areas of pesticides, chemicals, pharmaceuticals, and veterinary drugs, including the following. Specimen analysis: Methodological validation of specimen analysis and concentration analysis of specimens. Pharmacokinetics: We can provide clients with a complete set of in vivo pharmacokinetic GLP and non-GLP tests, including test protocol design, animal experiments, biological sample method development, method validation, sample analysis, data processing, test report writing, and drug formulation services. Toxicokinetics: We can provide customers with a complete set of in vivo toxicokinetic GLP and non-GLP tests, including test protocol design, animal experiments, biological sample method development, method validation, sample analysis, data processing, test report writing and drug formulation services. Detection of molecular weight of small molecule compounds, etc. Analytical Testing Laboratory Facilities High-performance Liquid Chromatograph Applying the principle of high-performance liquid chromatography, it is mainly used for the analysis of organic compounds with high boiling points, non-volatile, unstable by heat and large molecular weight. Uses: GLP system for preclinical drug safety evaluation of toxicology experiments, for the detection of the concentration of the test article. For the detection of the drug content of biological samples in the DMPK/TK test. For the detection of some cosmetic banned and restricted ingredients, pesticides, and other compounds. Liquid Phase Mass Spectrometer High sensitivity and good throughput performance. Uses: Mainly used in drug metabolism and pharmacokinetics research, plasma samples, and tissue homogenate samples for drug content analysis. It is used for the detection of banned and restricted ingredients in cosmetics, pesticide residues in Chinese herbal medicines, etc. Gas Chromatography-Mass Spectrometer Combining the characteristics of gas chromatography and mass spectrometry, it can identify different substances in the specimen. The real-time acquisition function provides full scan and selected ion scan data acquisition, which can obtain accurate qualitative and quantitative result data. Use: It is currently used for the analysis of pesticide residues in Chinese herbal medicines. Gas Chromatograph The instrument for qualitative and quantitative analysis of complex multi-component mixtures using chromatographic separation techniques and detection technologies. Use: Currently used for the detection of banned and restricted substances in cosmetics. Atomic Absorption Spectrophotometer Analysis of metal elements based on the absorption of characteristic radiation by an atomic vapor in the ground state of a substance. Use: For the analysis of metallic elements (lead, arsenic, mercury, cadmium, etc.) in cosmetics.
