Gas Chromatography

The process of Gas Chromatography is being utilized by scientists in order to be able to separate the volatile particles of a mixture. This is done with the aid of a syringe where the sample is drawn and then transferred to the port of the gas chromatograph called the into injector port. It is then set to reach a very high temperature which exceeds that appropriate boiling point for the substances, thus, allowing the particles to evaporate. Then helium is introduced in order to facilitate the flow of the evaporated substances to the gas chromatograph column where the separation will then take place.


  • Gas Chromatography Mass Spectrometry

    Gas spectrometry-mass spectrometry is a combination of both the process of GC and MS. 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...

  • Gas Chromatography Equipment

    Gas chromatography equipment is very essential for the process of separating and analysing compounds. Its parts are composed of the auto samplers, inlets, columns and detectors. These parts are very important for the stages of chromatography happen in these parts. This equipment was first devised by Fritz Prior, but at first, it was used for the solid state GC. But for over the years it was developed into different devices and finally...

  • Troubleshooting a Gas Chromatograph

    In getting or buying a gas chromatograph, it is not just the warranty that the company is giving that is needed to make you decide to buy from them. It is significant to check on how fast the firm could react on technical queries and technical assistance that they could provide in case the device need some repairs. A user’s training should also be required in order to pass on the technology to the end user.
