  • Method and system for solventless calibration of volatile or semi-volatile compounds
    Patent number: 12233395
    Abstract: A system for solventless calibration of volatile or semi-volatile compounds and methods thereof. The system includes a fluid path having a first end configured to be operably coupled to a fluid source and a second end configured to be operably coupled to the analytical instrument. A solid sorbent is disposed along the fluid path and is configured to absorb an analyte. The flow of fluid along the fluid path from the first end to the second end causes absorbed analyte to be desorbed from the solid sorbent at a desired concentration to the instrument.
    Type: Grant

  • METHOD OF IMPROVING A MASS SPECTROMETER, MODULE FOR IMPROVING A MASS SPECTROMETER AND AN IMPROVED MASS SPECTROMETER
    Publication number: 20240071738
    Abstract: The present invention relates to a method of improving a mass spectrometer, a module for improving a mass spectrometer and an improved mass spectrometer. The aforementioned method uses machine learning and can greatly reduce the number and timeframe for the elimination of false positives to a couple of hours. Such method can be integrated into a mass spectrometer by inserting a computer module programmed with such method into a mass spectrometer's computer system.

  • Method of improving a mass spectrometer, module for improving a mass spectrometer and an improved mass spectrometer
    Patent number: 11515133
    Abstract: The present invention relates to a method of improving a mass spectrometer, a module for improving a mass spectrometer and an improved mass spectrometer. The aforementioned method employs a calibration correction module that calibrates the mass spectrometer so timely, more precise and accurate data can be obtained. In particular, real time, accurate mass determinations of low analyte quantity samples can be obtained.
