Maximize Efficiency, Minimize Cost With SCION Equipment

Using SCION gas chromatography (GC) can save companies money in several ways. Here are some key points explaining how:
Technical Notes

Flame Ionization Detection

A flame ionization detector (FID) is a detector that is paired with a gas chromatograph (GC) for the analysis of organic compounds. An FID uses a flame, fuelled by hydrogen, to ionize the carbon atoms in organic compounds after they have been separated by the column in the GC.

Gas Chromatography: A Beginner's Guide

Gas chromatography (GC) is a type of chromatography that analyses volatile compounds. Gas chromatography uses an inert gas such as nitrogen or helium as the mobile phase and the stationary phase is contained in a column which is found inside an oven within the instrument.

Catalyst Definition & Meaning

A catalyst is a substance that accelerates a chemical reaction or reduces the required temperature or pressure to initiate one, without being consumed in the process. Catalysts enhance the efficiency of this process by lowering the activation energy, which is the energy barrier that must be overcome for a chemical reaction to take place

Comparison of FAME Analysis in Olive Oil by GC-FID and GC-MS

The determination of Fatty Acid Methyl Esters (FAME) is a commonly performed analysis, to determine the quality of extra virgin olive oil (EVOO). Natural EVOO is made by pressing or centrifuging olives, without exposing the olives to any chemical processing. A way of producing cheaper olive oil is to mix them with cheaper oils, such as sunflower oil and refined
