The temperature of the gas chromatograph 20ml screw headspace vials detector directly affects the selection of the bead heating power supply, the temperature control accuracy and the stability of the base flow. It is higher than the FID requirement in terms of temperature control accuracy, and is closer to the temperature control of the concentration gas chromatograph detector. Precision requirements. In actual operation, try to choose a higher height under the conditions of temperature permit. If you can maintain it at around 300 °C, there are several advantages:
1. The base flow interference of the large solvent peak or the large concentration component peak can be minimized;
2. The same performance can be achieved with a lower heating power source to extend the life of the beads;
3. The impact on the fluctuation of carrier gas, makeup gas and air is minimal;
4. It is beneficial to improve the temperature control 20ml screw headspace vials accuracy.
This is the end of the introduction of Gas chromatograph detector temperature. I hope it can help you.
