gas chromatography mass spectrometry Udehyci, Wed, May, 02, 2018

The gc chamber consists of a column. The quality of identifying the elements in the compound through its separation depends on the dimension of the column (length, thickness of the film, and the diameter). The time for which the elements of the compound to be separated and come out of the gas chamber called the retention time varies. Once the separated elements have come out of the gas chromatograph, it then proceeds to the mass spectrometer. Here, the separated elements are taken, ionized, accelerated, bent, and later on identify the elements separately by their mass to charge ratio.

The time it takes for the device to analyze a sample was also accelerated that is why in 1996, the innovated gc-ms device can process a sample at a span of only 90 seconds. This is a lot faster than the first device invented which can finish the process for as long as 16 minutes. Working the device, in order to execute the two processes, the device for gcms is combined in one instrument but is divided into two chambers. One is for the gas chromatography and the other for mass spectrometry.

Once the vaporized compound proceeds to the mass spectrometry process, it will be then separated and its components will be identified through the mass of the analyte molecule. History, during the 1950s, roland Gohlke and Fred McLafferty launched the idea of using mass spectrometry to identify the elements of a compound once they have been separated. Back then, the device they came up with were only limited for laboratory uses because of its room-size feature. However, through the innovation of technology, the size of the device was also minimized.

Gas Chromatography mass Spectrometry, gas spectrometry-mass spectrometry is a combination of both the process of gc and. Its purpose is to separate the chemical elements of a certain compound and identify the molecular level component. In the process, the mixture will be heated in order to separate the elements. Once it vaporizes, it passes the column through an inert gas, most likely to be helium, and proceeds to the mass spectrometry process.
