Gas Chromatography or Gas Liquid Chromatography is a technique applied for separation, identification and quantification of components of a mixture of organic compounds by selective partitioning between the stationary phase and mobile phase inside a column followed by sequential elution of separated component...

Gas chromatography columns GC columns represent the stationary phase and separation tool of a gas chromatography analysis. The stationary phase ensures that different compounds are adequately separated and eluted from the column at different times. Different t...
Our technical department is often involved in helping clients with “gas chromatography (GC) column autopsies.” Over the years, we have come to know the most common ways that you can effectively dispatch a column. However, like anything related to health, there are cures and preventative measur...
Gas chromatography 气相色谱Introduction Gaschromatography- specifically gas-liquid chromatography - involves a sample beingvapourisedand injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself ...
The function of the stationary phase in the column is to separate different components, causing each one to exit the column at a different time (retention time). Principle of Working of Gas Chromatography Flame ionization detector (FID) Flame ionization detector is a scientific instrument that ...
Gas chromatography column; formed in a conductive or semiconductive column material; organic layer formed by the reduction of an onium salt on the column bonded to inner wall of the column material surface; stationary phase material bonded to organic layer; uniform thickness ...
