High pressure in the Vialsampler is oftentimes due to a blockage in the needle seat assembly. The needle can pick up sample particulates or plugs from the vial caps when the Vialsampler is drawing the sample. When the valve switches back to mainpass, they are forced into the seat capillary and cause obstruction and high pressure.
