Flow path of the injection valve
If the injection valve is in the
<FILL>
position, the sample loop 61 is
filled by siphoning in the sample solution using the syringe. The eluent
flows directly to the separating column.
If the injection valve is in the
<INJECT>
position the eluent flows via the
sample loop to the separating column. This causes injection of the
sample previously added to the sample loop. Sample inlet tubing and
syringe are directly connected.
