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…
HI Arashjafari,
there is a nice overview article here: Chromatographic bioanalytical assays for targeted covalent kinase inhibitors and their metabolites - ScienceDirect
It should work with Poroshell 120 C18, Zorbax RRHD Extend-C18 or ZORBAX Eclipse…

Hello B
I would need to see your workspace to reveal what has gone wrong with the analysis. Please call us at 800-227-9770 with a serial number of your instrument.
Talk to you soon,
Howard
If you're running a custom macro you'll need to talk to whoever wrote it. Those abundances are incredibly tiny. Allowable electronic signal is somewhere around 50 counts, so unless that is background subtracted the only really useful ions there are 269…
The operator is using the requeue batch option from an already run batch instead of creating a new batch. Mass Hunter will append the # in this case. I suggest creating a batch template from your desired method and using that for future batches. This…
