Dry separate sampling probe cavity volume, puts into sampling probe in different sampling probe cavity volume and is carried out, effectively keep away
Exempt from the cross-contamination caused between sampling probe outer wall, improve the credibility of chemical experiment result.2, the present invention by
In using high pressure cleaning pump that cleaning solvent is injected to sampling probe cavity volume, forming a kind of actively jet flow cleaning mode has
Improve to effect the dirt-removing power of cleaning solvent.3, after due to the fact that employing waste fluid channel will clean sampling probe
Waste liquid is discharged in time, it is to avoid the waste liquid pollution to sampling probe.4, due to the fact that employing cleaning solvent selector valve,
Select different cleaning solvents for different needs, substantially increase cleaning efficiency.In sum, the present invention
Can be widely applied in sampling probe cleaning field.
