What is the weight spectrometer of the gas chromatograph?

The mass spectrometer of the gaseous chromatograph (GCMS) combines gas chromatography and mass spectrometry for the identification and quantification of substances. The process begins by the fact that the substance that is studied is diluted with gas or liquid and introduced into the machine. GCMS separates the substance on components to be identified by a computer. The weight spectrometers of the gas chromatograph have a wide range of uses, including unlawful drug investigations, environmental detection and medical diagnosis.

Gaseous chromatography or GC phase of analysis usually includes the location of the sample in the injection device portal. The substance can be dissolved in aqueous solution and injected into a hypodermic needle. As soon as the glass or stainless steel chamber goes to the oven where it is transformed into gas.

gradually increases the temperature causes the compound to break into its components, leaves the chamber and passes the variable speed to the Detector. Electrically charged, particles start electronic signall. The greater the particle concentration, the stronger the signal is formed.

These signals are then analyzed using computer software. The computer produces a chromatogram with peaks that indicate the retention times and the intensity of the compound signal. Knowing the time of maintaining different chemical compounds allows investigators to identify them.

Another analysis occurs in the mass spectrometer. Once the compounds enter the spectrometer, it encounters a series of electrons or gas. There is ionization, breaking the compound into fragments, each with a specific atomic mass. These fragments are subject to analysis by compilation of the weight of the mass fragment to the charge or m/z.

6 Intensenity. Computer software usually contains a database of known M/Z ratios and signal intensity for various chemical molecules. The computer identifies substances and compares the information obtained with the library of familiar substances. WeightThe gaseous chromatograph case can complete each phase of the analysis individually or at the same time. Depending on the level of the required details, the completion of the process may take 20 minutes or more than 20 hours.

Criminal officials use the mass spectrometer of the gas chromatograph when they suspect the presence of illegal drugs or toxic substances. Environmental agencies use this technology to analyze air, soil or water to detect possible pollutants. Health workers use GCM on urine samples to detect chemical compounds found in individuals with certain metabolic disorders.
