What is Gas Chromatography?
Gas chromatography is the process of separating compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase, typically called the carrier gas, and passing the gas through a stationary phase.
The mobile phase is usually an inert gas or an unreactive gas such as helium, argon, nitrogen, or hydrogen.
Gas Chromatography Prices In South Africa
The gas chromatography system is built with commonly available materials with a total cost of less than R1670.95.
A Python code is also provided as a user interface that will record data and display the results in real-time.
What are the two types of gas chromatography?
Two types of gas chromatography are encountered: gas-solid chromatography (GSC) and gas-liquid chromatography (GLC).
Gas-solid chromatography is based upon a solid stationary phase on which retention of analytes is the consequence of physical adsorption.
Which chromatography is best?
Chromatography methods based on partition are very effective in the separation, and identification of small molecules such as amino acids, carbohydrates, and fatty acids.
However, affinity chromatographies (ie. ion-exchange chromatography) are more effective in the separation of macromolecules such as nucleic acids, and proteins.
What are the common uses of gas chromatography?
Manufacturing relies on gas chromatography for quality control, companies that produce cars, chemicals, and pharmaceuticals, in particular, are big adopters of the technology.
The pharmaceutical industry uses gas chromatography to help produce pure products in large quantities.
How long does gas chromatography take?
Either gaseous or liquid samples, as small as several micro-liters, can be analyzed. And the whole process of GC/MS analysis takes about one hour or less, depending on the complexity of the compound to be analyzed. The two major components of GC/MS are the gas chromatograph and the mass spectrometer.
