This can happen when one of the motors on the arm of a vial sampler (G1313, G1329, or G7129) is failing. It will be fine for a number of injections, then one of the motors gets too hot from all the movement and will cause the sampler to error. When you…

Yes, that what I was looking for. But in the same time, we realized that Office 2016 is able to correctly open "coma" or "semicolon" separeated .csv, where Office 2010 fails and only opens one format correctly. So we're looking at this option as well…
We are trying to resuscitate a G1956A MSD. Recently replaced power supply which got the heaters working but MSD still not ready. On running diagnostics, got an MS Ion Optics Test Failure: Ramping Test Error: Not enough signal at m/z 1218 for ramping test…
We have Agilent G1312B, 1367C autosampler and G1316B column compartment, we just installed openlab C.01.09 into our surface book laptop with window 10 pro, when we did the installation, system check found some problems, such as power options and window…
I have an Agilent 7890A GC-FID with dual split/splitless inlets and detectors configured with a 0.53 mm ID capillary column. My instrument keeps giving me the message "front inlet pressure, system shutdown". The front inlet cannot maintain pressure and…
1.0 What is the significance of detector noise during GC calibration 2.0 What is the impact if it fails 3.0 What is the difference between signal to noise ratio and detector noise and drift
Maintenance have been done on the P&T, the buller is cleaned, the trap have been change in august 2016, moisture trap in december 2016. The method we're using is the method used here over years...Never had this kind of problem... The GC column had been…
Hello everyone! We have a Lc MSD VL G1956A single quad. In the past, at some point we had problems with the acquisition of MS. We had lost the MSd signal. Now it's worse. It is impossible to make acquisitions with MS.
The equipment is under maintenance…
