What is Gas Chromatography? Gas Chromatography also known as vapor-phase chromatography (VPC), or gas–liquid partition chromatography (GLPC) is most widely used analytical technique in the world; it is used for the separating and analysing compounds that can be vaporized without decomposing. Among its uses are being able to test the purity of a substance, being able to separate different components in a mixture and help in environmental contaminant identification . This can lead to GC being able
Gas chromatography is widely used for analytical purposes in the chemical world to separate and analyse volatile compounds. It is mostly widely known as being paired with a mass spectrometer as, whilst it is a useful technique for testing purity and separating and quantifying compounds, it is less useful for definitive characterisation or identification. In this technique, a sample, which must consist of sufficiently volatile liquids or solids, is injected through a septum into a heated port, which
The way many humans exploit animals for food, cosmetics, products, and medical experimentation is madness. However, there is a method to this madness; it is known as the “factory formula.” This formula is the principle underlying all factory methods and equipment; it is meant to keep costs down and manipulate animals’ productivity upward. Consequently, animals are crowded, restricted, stressed, frustrated, held in barren environments, and maintained on additive-laced, unnatural diets (Singer ed.
