Autosampler Principle
Flush the Needle Before injection and to reduce the carry- over for very sensitive analysis,
the outside of the needle can be washed in a flush port located behind
the injector port on the sampling unit. As soon as the needle is on the
flush port a peristaltic pump delivers some solvent during a defined time
to clean the outside of the needle. At the end of this process the needle
returns to the injection port.
