of the cover.

Caution: To replace a new nozzle, make sure that the nozzle airproof gasket (accessory#14) should also be replaced by
a new one. Then turn the nozzle tight to prevent gas leakage.

8.2.2 Clean the Sampler

The sampler can easily be contaminated, especially the gasification tube. Therefore it is quite important to clean the
sampler. First take off the chromatography column, remove the heat dissipation gasket and take out the airproof silica
gel gasket and the gasification tube. Then clean the heat dissipation gasket and the gasification tube with acetone or
alcohol and dry them. The inside wall of the sampler tube can be directly cleaned by acetone or alcohol sponge
repeatedly. Then blow a large flow of carrier gas into the tube (mainly to blow out the cotton fiber and dry the solvent).
Then assemble the gasification tube and the chromatography column, place in a new airproof silica gel gasket and turn
the heat dissipation gasket tight.
