1 Introduction
Autosampler Principle
The standard injection starts with draw sample from vial. In order to do
this the needle moves to the desired sample position and is lowered into
the sample liquid in the sample to allow the metering device to draw up
the desired volume by moving its plunger back a certain distance. The
needle is then raised again and moved onto the seat to close the sample
loop. In case of an injector program several steps are interspersed at this
point.
