Sample supply system

Sample supply is carried out as flow injection via syringe pump with 2-port valve. The in-
jection volume is 50 to 3000 µl.

The hose connections are attached to the 2-port valve using Fingertight screw connec-
tions. The syringe body is made of glass and replaceable.

The hoses on the 2-port valve are connected to the following components:

Hose AA to the sample

Hose AB to the change-over valve
