Yadda za a kula da gasar chromatograph liner da kuma samfurin kofa?

Kodayake rarrabuwa / ba rarrabuwa samfurin shigarwa, cika ginshiƙin samfurin shigarwa da kuma babban diamita capillary ginshiƙin samfurin shigarwa, don liner tsarin bukatun ba su da kama, amma daban-daban tsarin liner kulawa hanyoyin da suke da kama. Don rage tasirin sakamakon ƙididdiga saboda gurbataccen hose da ƙofar samfurin, ya kamata a bincika da tsabtace hose da ƙofar samfurin ciki, ƙofar samfurin sauyawa, da sauransu, kuma a maye gurbin hose idan ya zama dole. Don kulawa da hose da kuma shigar da samfurin, yawanci an raba shi zuwa kulawa na yau da kullun da kulawa na yau da kullun.

1, kulawa na liner:

① Kulawa ta yau da kullun na liner

Tsabtace liner, ne yau da kullun amfani da kulawa hanyar, dace da liner ciki bango ne gurbataccen ko da samfurin keɓaɓɓen keɓaɓɓen.
