1 Introduction
Autosampler Principle
Injection Sequence
Before the start of the injection sequence, and during an analysis, the
injection valve is in the mainpass position. In this position, the mobile
phase flows through the autosampler metering device, sample loop, and
needle, ensuring all parts in contact with sample are flushed during the
run, thus minimizing carry- over.
