Liquid Chromatography-Mass Spectrometry (LC-MS)

Liquid chromatography-mass spectrometry (LC-MS) has developed to become a powerful, indisposable and essential bioanalytical technology. A high-throughput LC-MS process require conditions for separation and detection of excellent reproducibility, robustness, and low fault liability. Early drug discovery projects make full use of LC-MS screening approaches which selectively detect chemical functionalities of target molecules. Liquid chromatography conduct safe separation of a wide range of organic compounds from small-molecule drug metabolites to peptides and proteins. Chromatographic process is therefore applied as a separation technique in mass spectrometry helping in both qualitative and quantitative analysis of candidate drugs.

Advantages of LC -MS

LC-MS has several advantages over MS and they can be summarized as the following aspects:

  • A large numbers of drugs can be identified in just one condensed analysis window.
  • As a presumptive method, LC-MS greatly reduces the use of reagent which is cost-effective for the drug discovery project.
  • LC-MS can rapidly generate better data quality and is easy to operate.

Process of LC -MS

The whole process of LC-MS can involve the following three steps:

  • Separate mixtures in accordance with their physical and chemical properties.
  • Identify the components within each peak.
  • Detect each of them on the basis of their mass spectrum.
