Sample supply system

16
Sample supply is carried out as flow injection via a syringe pump with 9-port valve. The
injection volume is 50 to 20000 µl.
For small sample volumes (V < 1.5 ml), system water is additionally added to the reactor
with each dosage.
The hose connections are attached to the 9-port valve using Fingertight screw connec-
tions. The syringe body is made of glass and replaceable.
