Question

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 configuring the system by using the Acquistion Tools, Instrument Config. I am hoping this isn't a corrupted

installation. I seem to be able to set the wavelength in an online session. Is there anything I could be missing ?

I am not getting a real-time signal from the diode-array either.

Those LC firmware revisions are newer than your B.04 software but I would expect them to be backwards compatible. Your QTOF firmware shows that this system was not successfully upgraded to Service Pack 3 (it should be firmware 7.428). I don't know if the service pack will fix your problem-it doesn't seem to be documented, but it might be worth a try. The file is large; 13 MB. Look around to see if you have it on CD/DVD.
