First, the chromatograph identifier is not hot
Failure phenomenon:
(1) Pull the ignition switch, the ignition resistance will not heat up, and there is no sign of ignition.
(2) When using an igniter or lighter for manual ignition, there is no "spray" ignition sound or nail "spray" ignition sound, but it still does not ignite.

Second, the column thermostat does not heat up
Failure phenomenon:
(1) After the temperature of the incubator is set normally, the column incubator ‘displays the ambient temperature value and the temperature of the temperature sensor is warmed, but the displayed temperature value changes slightly.
(2) No display on the display panel of the thermostat when it is turned on.
Third, the integrator tomb line is unstable
Failure phenomenon:
(1) There are interference glitches or pulses on the integrator baseline.
(2) The baseline noise of the integrator is large, and the stupid line is thick.
Fourth, the common troubleshooting of the gas circuit
Failure phenomenon:
(1) On the integrator, the baseline is unstable and the noise is loud.
(2) The sample does not produce peaks or the retention time of the peaks is incorrect, and the interference is large.
