(GC) is an analytical technique used to separate and detect the chemical components of a sample mixture to determine their presence or absence and/or quantities. These chemical components are usually ...

Gas chromatography can be used in combination with molecular spectroscopy to provide structural and quantitative information on a variety of sample types. Molecular spectroscopy techniques, most ...

In this article, we discuss the fundamentals of headspace extraction, including static versus dynamic extraction, establishing equilibrium in the vial, consequences of the partition coefficient, ...

There is a strong focus on environmental monitoring to reduce these emissions. However, traditional sensor systems are unable to meet the speed and accuracy requirements needed today. To compound the ...

AT the Third International Symposium on Microchemistry in Birmingham, Prof. F. Feigl reported on the combination of coloured spot reactions with the pyrolysis of high molecular weight substances for ...

In gas chromatography (GC), the mobile phase is an inert gas (eg helium). The stationary phase is a very thin layer of an inert liquid on an inert solid support - such as beads of silica packed into a ...

Analysts interested in quantifying volatile organic compounds like disinfection byproducts in liquid samples should consider using the gas chromatography system. There are two gas chromatography (GC) ...

Chromatography is a process for separating components of a mixture for analysis. This is a component of our small molecule analysis testing and plays a critical part in identifying and quantifying ...
