Beijing Yuangui Company (starting training on July 13th and arriving in Suzhou on the afternoon of July 12th) will hold an installation and maintenance training course at the GC-MS factory until next Friday (July 17th).

GC-MS (Gas Chromatography Mass Spectrometer) refers to a gas chromatography-mass spectrometer, which is an analytical instrument used to measure the ion charge to mass ratio (charge to mass ratio). In this type of instrument, due to the different working principles of mass spectrometers, there are gas chromatography quadrupole mass spectrometer, gas chromatography time-of-flight mass spectrometer, gas chromatography ion trap mass spectrometer, etc.

firstThe mass spectrometer was developed by British scientist Francis Aston in 1919. Aston made remarkable achievements by using this device to discover multiple isotopes of elements, studying 53 non radioactive elements, and discovering 212 out of 287 naturally occurring nuclides,firstThis proves the loss of atomic mass. He was awarded the Nobel Prize in Chemistry in 1922 for this.
