How to improve the sensitivity of gas chromatography?
There are several ways to improve sensitivity. Adjust the best operating conditions of the instrument. If FID detector is used, the sensitivity can be changed by changing the range. In addition, when the ratio of H2 to oxygen is 1: 10 (ml/min), the detector has the highest sensitivity. If TCD is used, H2 can be used as carrier gas instead of N2, which can improve the sensitivity, or increasing the bridge current can also improve the sensitivity.
