Introduction
Operating Principle
When the metering unit has drawn the required volume of sample into the
sample loop, the vial is replaced in the sample tray. The wash port flips into
the origin position, the needle is lowered into the needle seat, and the
injection valve switches back to mainpass (main path) position, flushing the
sample onto the column (see
Figure 7
