Embodiment 1
[0017] In view of the HP-MOLESIEVE capillary chromatographic column failure, which can only be replaced in the past, the present invention develops a regeneration process for the HP-MOLESIEVE glass capillary chromatographic column failure. Its process method is as follows:
[0018] Remove the front capillary chromatographic column (HPPLOT-Q 30m, 0.53mm, 40um), and then connect the inlet end of the back capillary chromatographic column (HP-MOLESIEVE 15m, 0.53mm, 50.0um) to the inlet, and the outlet end is air-proof, according to The 6890N gas chromatograph needs to be turned on to start the chromatograph. After the self-test of the instrument is completed, check whether there is gas outflow from the outlet of the chromatographic column. If there is gas outflow, it means that the connection is correct. Then set the working conditions of the 6890N gas chromatograph as follows: change the protection temperature of the column oven from 150°C to 400°C, and make the injector heating,...
