The images below show Omnifit loop inject valves in use as sample injection devices in a chromatography system. These are
the most common applications but the use of the valves is not limited to these.
Application and set up notes.
6 port loop inject valve used as a sample injector
With the valve in the load position the sample can be injected into the
sample loop while the mobile phase is pumped directly through to the
column.
When the valve is switched to the inject position, the pump is then
connected to the sample loop and the sample is carried onto and
through the column. The ‘sample in’ and ‘waste’ ports are joined but
isolated from the loop.
It is suggested that ports are connected to the corresponding lines as
shown. This ensures that the flow of the mobile phase is in opposite
directions during the load and inject operations.
10 port loop inject valve used as a sample injector
This valve allows alternate injection from two different sample loops,
either identical or of different sizes. This application can alternatively be
satisfied with a 4 port switching valve and a 6 port loop inject valve.
With the valve in position A, sample 2 can be loaded into sample loop 2
while the mobile phase is pumped through sample loop 1 and carries
sample 1 onto the column. The ‘sample 1 in’ and ‘waste’ ports are
connected but isolated from the loop.
When the valve is switched to position B, the pump is connected to
sample loop 2 and sample 2 is carried onto and through the column.
The ‘sample 2 in’ and ‘waste’ ports are connected but isolated from the
loop. Whilst sample 2 is pumped onto the column, sample loop 1 can
be re-loaded.
