How to control the temperature in gas chromatography progress?


Temperature control is a critical part in the process of Gas chromatography analysis of the sample. Because the temperature determines what type of headspace vial is selected.

The principle of temperature control: heating temperature, transmission line temperature, quantitative ring temperature should be increased in turn. The aim is to prevent the incoming gas from condensing during transmission, causing residue.
Secondly, in the process of heating, the heating time needs to be examined to ensure that the balance of the temperature of each port.
headspace vial intrument
Gas chromatography is mainly used to determine the composition of solvent volatilization, so the boiling point of the sample is not investigated; As long as the sample which be tested can volatilize. The heating temperature of the sample is different from the boiling point of the sample. Some sample are volatile, lower temperature can also be overhead detection, some sample’s volatility is poorer, heating temperature will be higher, as long as the sensitivity to meet the detection requirements can be. Please note that the heating temperature should not be too high, because the headspace vial is sealed, If the temperature is too high, it may cause air leakage or even the headspace vial explosion.
