The pulsation absorber is completely connected. No installation work is
required.
3.9 Injection valve
The injection valve connects the eluent path to the sample path. By a
quick and precise switching of the valve a defined quantity of sample solu-
tion is injected and flushed to the separation column with the eluent.
The quantity of sample solution injected is determined by:
￭
the volume of the sample loop or
￭
by an 800 Dosino when the Metrohm intelligent Partial Loop Injection
Technique (MiPT) is used.
The choice of sample loop depends on the application. The following
sample loops are normally used:
Table 1 Which sample loop do I need?
Application Sample loop
Cation determination 20 µL
Anion determination with suppression 20 µL
Anion determination without suppression 100 µL
MiPT 250 µL
The injection valve is completely connected. No installation work is
required.
Optional: Exchanging the sample loop
The sample loop can be replaced to match the application (see Table 1,
page 26) .
NOTE
Only use PEEK pressure screws (6.2744.010) to connect capillaries and
the sample loop to the injection valve.
