Hello,
Typically, it is difficult to determine the issues with AV and security software within the logs. You could look into the acquisition server logs around the time the crash happened. I would also look at the windows event logs for other activity…
The Agilent TRS100 Quantitative Pharmaceutical Analysis system has been certified with My Green Lab’s ACT label in the EU, UK, and US. This clear, third-party verified information about the system’s environmental impact makes it easy for laboratories…
The phenomenon you describe is inevitable for broad polymer samples: The signal intensity (SI), of all detectors depends on injected mass (concentration and injection volume), a sample related constant k Sample (i.e., response factor), and a detector…
Hi,
In your case, the path of the column database must be adjusted. This is done as follows:
1) Close WinGPC software 2) Search registry editor (Windows logo key + "regedit") and run it as administrator (possibly involve your IT department) 3) Find…
Hello bofzgi84 ,
As an update to this, a colleague of mine has pointed out that for LC data the Compound ion count threshold settings are not present. I took the above screenshot with no data file loaded, so all possible options were enabled. I can…
Was the air/water check before you changed the septum and liner acceptable? 60% Oxygen...what is the Nitrogen percentage? 60% Oxygen would either be a gigantic leak and the Nitrogen percentage will be off the charts, or there is oxygen in the carrier…
