Introduction to the Well-plate Sampler

Injection Sequence

Before the start of the injection sequence, and during an analysis, the injection
valve is in the mainpass position
flows through the well-plate sampler metering device, sample loop, and
needle, ensuring all parts in contact with sample are flushed during the run,
thus minimizing carry-over

When the sample sequence begins, the valve unit switches to the bypass
position
and flows directly to the column through port 6.
