Hi Mau1909
We can perform this type of measurements with the Cary Eclipse. This is called EEM (Excitation-Emission-Matrix):
3D graph or contour plot are available. The 3D mode automatically collects a series of excitation, emission, or synchronous…
The universal VUV detector has sensitivity better than an FID and similar to an MSD while allowing data acquisition across 12 different wavelength bands to focus on selected compounds of interest. It can be mounted directly on top of an Agilent 7890 or…
Hi,
I have been getting a Hexapole 2 RF fault on a 6545 QTOF for the past few weeks. The logbook shows that it came on for short periods for a couple of days, then went away for a few days, then came on continuously since then.
I called it in, and…
Hello mohls ,
The default location for the log file should be within the D:\MassHunter folder. Since it appears to be trying to write the log to the C:\Program Files folder, which will never succeed, I suspect that something has occurred with the BioConfirm…

Ok so I guess you have to manually move the arm out because the inside screw is covered by the turret. It seems hard to move though and I don't want to break it.
According to the user manual you are able to change the following things in a timetable on a G7121A:
I actually never used a timetable on a G7121A model. Like the G1321C, the G7121A just offers one pair of EX/EM, so signal A only. For enhanced signal…
