I am getting an incorrect collection volume and there is a droplet on the collection needle, what should I do?
Concerned instruments: puriFlash 215, puriFlash 430, puriFlash 450, puriFlash 4100, puriFlash 4250
Concerned module: collector
The collection valve is defective.
Clean the collection valve with an appropriate solvent (highly eluent solvent).
If cleaning has not effect, the collection valve will need to be replaced.
