Hi, Using one and the same column for different applications is possible, as long both solvents are permitted (column user manual e.g.).
The column should always be flushed very slowly from solvent A to B (0.1 mL/min). At least 5 times the column volume…
Hi Marty,
Thanks for taking the time to respond. I saved the data to a file and then printed the file and it was properly formatted. I think that there is an issue with printing to paper from the method. Since this is a long unsupported CS revision…
Hi Abbey
Thanks for the info!
So far we have only been running this on various forms of olive oil. But the waves in the baseline remain regardless of MOAH contant. I have run samples that were analyzed by outside labs (with COA) that contain 0ppm…
From a quick google search, it appears that hydroquinone may be detectable through LC/MS (ESI) in both positive and negative mode. It forms a protonated molecule ([M+H]+) at m/z 111 in positive mode and two ions at m/z 108 and 109 in negative mode.

奔跑的小短腿 , While an LC/MS system may operate in both positive and negative ion polarity modes, it will switch between the two polarities based on the user input in the acquisition software. It is not possible to acquire in both polarities simultaneously…
Hi Vincenzo,
Thank you for your answer. We have the CFR environment. WinUV 5.1.3.1042. (1042 indicates Part11).
I’ve looked for method files for the following apps; Advanced Reads which are .MAB, Concentration .MCN, Scan .MSW, and Simple Reads .MSR…
