Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [ 1 ]

Electron capture detector developed by James Lovelock in the Science Museum, London Electron capture detector, Science History Institute. The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph.
A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.
Peak Integration parameters and settings: Use appropriate algorithms to integrate the peaks in the chromatogram. Adjust integration parameters and settings as needed, such as noting peak width, noise threshold, and baseline correction method, which determine where the peak starts and ends and its maximum point.
GC–MS is used for the analysis of unknown organic compound mixtures. One critical use of this technology is the use of GC–MS to determine the composition of bio-oils processed from raw biomass. [29] GC–MS is also utilized in the identification of continuous phase component in a smart material, magnetorheological (MR) fluid. [30]
Electrocardiography machine : to read and trace the electrical activity of the heart; most toxins have an effect on the heart video link: Blood gas analyzer: used to analyze and quantify the amount of various toxic gases within blood like Carbon monoxide: Electroencephalography : to read and trace the electrical activity of the brain; video link
Gas chromatography-mass spectrometry (GC-MS) is a two-dimensional chromatography technique that combines the separation technique of gas chromatography with the identification technique of mass spectrometry. GC-MS is the single most important analytical tool for the analysis of volatile and semi-volatile organic compounds in complex mixtures. [7]
