Common faults and solutions for chromatographs

First, the chromatograph evaluator is not a fire failure phenomenon:

(1) Pull the ignition switch and the ignition resistance is not heated, no signs of ignition.

(2) When manually igniting with an igniter or a lighter, there is no "spray" ignition sound or nail "spray" ignition sound, but it still does not catch fire.

Second, the chromatograph color column thermostat does not heat up the phenomenon:

(1) After the oven temperature is set normally, the column oven will not directly display the ambient temperature value, but the temperature value will change slightly.

(2) The display panel of the temperature controller is not displayed.

Third, the chromatograph integrator tomb line instability phenomenon:

(1) The integrator has a glitch or pulse that interferes with the baseline.

(2) The integrator's baseline noise is large, and the stupid line is thick.

Fourth, the chromatograph gas path common troubleshooting phenomenon:

(1) The baseline is unstable and the noise is large on the integrator.

(2) The retention time of the sample without peak or peak is wrong, and the interference is large.
