MS-Express software efficiently processes mass spectrometry data from high-throughput experiments (HTE). This tool automates data extraction and analysis, identifying expected and unexpected signals for catalyst research.

Area of Science:

  • Catalysis Research
  • Analytical Chemistry
  • Chemical Engineering

Background:

  • High-throughput experiments (HTE) generate substantial raw data requiring evaluation for sample classification.
  • Mass spectrometry (MS) is a key detection method in catalytic HTE, producing vast datasets.
  • Current HTE MS data evaluation involves tedious manual extraction and averaging of scans.

Purpose of the Study:

  • To introduce MS-Express, a custom software tool for efficient HTE MS data evaluation.
  • To automate the processing of large MS datasets generated in catalytic HTE.
  • To facilitate the identification of both expected and unexpected signals for catalyst discovery.

Main Methods:

  • Development of MS-Express software for automated data extraction and processing.
