GASCHROMATOGRAPH

On this page we will try to inform you more about a gaschromatograph, also called GC. You use a GC when you want the answer for this question: What does the liquid contain and in what amount?... A gaschromatograph is a chemical analysis instrument for separating chemicals in a complex sample. A gas chromatograph uses a flow-through narrow tube known as the column, through which different chemical constituents of a sample pass in a gas stream, this is called carrier gas, also known as 'mobile phase'. At different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the 'stationary phase'. As the chemicals exit the end of the column, they are detected and identified electronically. The function of the stationary phase in the column is to separate different components, causing each one to exit the column at a retention time... Their a three types of gas which you use in the mobile phase in a gaschromatograph
