Hi Tenamyd
Maybe a bit more detail would help to get you an answer. Here's a few questions:
Is the method gradient or isocratic
Do you prepare the mobile phase freshly each day
Is the column maintained at a set temperature using a column oven…
You will need to plot the piston movement as well. The upper plateau is the secondary piston moving. If the spike is at the beginning of the plateau, then it is more likely the Outlet ball valve. If the spike is at the end of the plateau, it is more likely…
Hello,
Sorry for the late reply. Thank you so much, that actually worked perfectly and I can now produce a report template fit for our purpose. Thanks again and I really appreciate the assistance.
This shows where to drill a 2.5" (6.35 cm) hole in the bench to be able to pass the rough pump hose fittings through to be put the rough pump on a shelf below the bench. Information on how to vent the rough pump to a lab exhaust system is also included…

Hi Mike,
I followed your advice but have not been successful getting any of these methods to work. When I try the first method, I get an error message at the bottom of the screen "Syntax Error in cmd/fct EVALUATE" that prevents the data from being exported…
Hello Tom,
Thank you so much for your reply. This is really helpful. I am running MH V4.6. If you could send me the screen captures for this version would be greatly appreciated!

Hello,
You can view the completed injections in a sequence in the reprocessing session(offline) of the instrument. If you are talking about viewing the data for the in-progress injection, you will need to take a snapshot. I did not have anything running…
