Under continuous sampling conditions, the peak area of the gas chromatograph fluctuates greatly, resulting in poor measurement accuracy. The reasons are as follows:

Sample technology is subpar.

2. Gas carrier leakage or unstable flow rate

3. Chromatography Detector Contamination

4. Contaminated chromatography columns and gas chromatography liners; clean the liners, clean the chromatography columns with solvent: replace if necessary.

5. Sample volume exceeds the linear range of the gas chromatography detector, causing the detector to overload.
