Temperature control of gas chromatography

The three systems are carrier gas system, sampling system and monitoring system.

The first thing about temperature control is the column temperature, which should be between the highest and lowest operating temperature. Considering the separation and diffusion rate, the column temperature is low, but the retention time is appropriate and the peak shape is symmetrical under the premise of separating the most difficult components as well as possible!

Followed by vaporization temperature. Between the vaporization temperature and the separation temperature (that is, to ensure that the sample does not decompose), the vaporization temperature is generally 30~70 degrees Celsius higher than the column temperature.

Finally, the detection system ensures the combustion temperature!
