Is there a way to manually toggle the valve(s) of a Lachat QuickChem analyzer?
Manually toggling the Lachat valve
Yes. In the Timing tab of the run properties window in Omnion, small colored icons indicate what state the valve for each channel is in. Clicking within the box manually changes the state of the valve. When the valve icon is red, sample should be going through the sample loop and the valve is in the load state. When the valve icon is green the valve is in the inject state. This is very helpful for determining if the valve is turning properly as well as for back flushing and cleaning the valve.
