Hello, you can export sequences into a new project file.
- Select a sequence of a loaded project and click Export data in the [project management] window.
- The now open window allows you to select more sequences from this project to export (see…
Depending on the software, linear and/or polynomial regression models are supported. Strictly speaking, linear fits can only be used for linear columns. However, it is also observed here that a polynomial fit may be more suitable depending on the column…
As you have already mentioned, HFIP is a very aggressive solvent that has a high density at a low boiling point.
Note that only the external degassers G1322/G7122 are compatible with HFIP. HFIP analyses are usually run with KTFAc as a salt additive…
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…
