I wanted to ask if there is some kind of "script" in the MassHunter Software, that enables the shutdown of the DAD and the QQQ of our 6460 device seperately after a worklist. If we run a worklist on Friday for example we don't want the DAD and QQQ to run the whole weekend but of course we want to keep a minimal flow of buffer over the weekend as… Show more
Hello, I updated the tags on this post to increase visibility. A number of Send_Module commands need to be run at the end of the Worklist to accomplish the requested tasks. This Scripts are added in the Worklist by a right clicking on a row in the Worklist and selecting Insert Script. The first command is to put the instrument in…
I am having some trouble with MassHunter Data Acquisition. Specifically, the DAD is not accepting wavelength assignments when loading up a method. MassHunter always says that it cannot load in wavelengths and will use default settings. I think the inst
Good morning, fellow colleagues. I have started to use MassHunter B.04.00 with my 6520B LC-QTOF. I am having some trouble setting up the diode-array detector on the HPLC from MassHunter. When loading in a HPLC method, the computer responds, Failed to load, using default wavelengths Okay to continue (or along those lines). I have tried… Show more
Hi Thank you, This Capillary Electrophoresis instrument was utilizing OpenLAB 3.4 software. It has had a previous history of losing connection to ECM and having data stuck in the data queue manager. There was an incident in the beginning of the year where analysts were inadvertently ignoring the data queue pop up and the queue was so…
Hi All, I would like to inject 0.5uL with a 10uL syringe on Agilent GC6890N (software version Rev B.03.02(341)) with an Agilent injector model G4513A. Unfortunately, the GC 6890N could not regconize the injector. Could you please advise what should I do or update to allow GC 6890N identify the injector? Many thanks!

Hi All, I need help to fix either baseline drifted down or change volume injection of water samples in GC/FID. Specifically, I am setting up a new GC instrument for analysis of methanol and alcohols in water samples with the following conditions: - Instrument: Agilent 6890 with FID detector - Column: DB1, 60m length, 0.53mm, film 3 micron,… Show more
