Iron(II)fumarate is a salt with a melting point of 280 °C and therefore not suitable for gas chromatographic analysis. You need to remove the metal ion and set the fumaric acid free, get the sample dry to derivatize it with BSTFA or do an esterification…
Hello,
The infinity II is the HPLC hardware, that can be controlled by several different Agilent software platforms CDS 2.x, Chemstation, EZChrom plus third party data systems. In most of the Agilent software, if you can find the help menus, there…
Hello,
You cannot change the presentation of that results preview screen directly in Chemstation. You might be able to change the behavior using macros, but no configuration is available by default.

Hello,
Based on the ladder profile in the screenshot you shared, it appears that you are running the DNF-905 kit.
In reference to the issue of missing sample signal or blank lanes, since ladder and marker peaks are present as expected, issue is likely…
K_Ruiter The error you are experiencing could be related to the ESW/FW version used on the Ultivo (I would assume you are using ESW 6.74.3). If you are willing to upgrade acquisition software to the latest (MH 12.1), the new ESW/FW for the TQ may resolve…
Hello,
I am not sure as I do not have systems setup that are that old. It would be based on the driver from that version. Do you see the option for serial communication when configuring the HPLC in B.04.03, if not then I would say serial was phased…
