High-performance liquid chromatograph

In the GLP system, during toxicological studies for preclinical drug safety evaluation, the concentration of the test substance is determined.

High-performance liquid chromatograph

   Instrument Name: High-performance liquid chromatograph
   Model: E00641
   Manufacturer: Waters Technology (Shanghai) Co., Ltd.
   Introduction: An instrument and equipment that utilizes the principle of high-performance liquid chromatography, primarily used for analyzing organic compounds with high boiling points, low volatility, thermal instability, and large molecular weights. It consists of several key components, including a solvent reservoir, a pump, an injector, a chromatographic column, a detector, and a recorder.
   Use: In the GLP system, it is used for detecting the concentration of test articles in preclinical drug safety evaluation toxicology studies; it can also be applied to the detection of drug concentrations in biological samples during DMPK/TK studies. Additionally, it can be used for the detection of certain prohibited or restricted ingredients in cosmetics, pesticides, and other compounds, and its scope of application is continually expanding.


  Some of the testing services provided by our company’s Analytical Testing Department passed the pharmaceutical GLP inspection in 2021. Currently, our experimental services in the fields of pesticides, chemicals, pharmaceuticals, veterinary drugs, and others include:
  1. Test Sample Analysis: Validation of the analytical methodology for test samples, and analysis of test sample concentrations.
  2. Pharmacokinetics: We can provide clients with a comprehensive suite of in vivo pharmacokinetic GLP and non-GLP studies, including study protocol design, animal experiments, bio-sample method development, method validation, sample analysis, data processing, report writing, and pharmaceutical formulation services.
  3. Toxicokinetics: We can provide clients with a comprehensive suite of in vivo toxicokinetic GLP and non-GLP studies, including study protocol design, animal experiments, bio-sample method development, method validation, sample analysis, data processing, report writing, and pharmaceutical formulation services.
  4. Detection of molecular weights of small-molecule compounds, etc.
