Yes, it is the constant flow mode. The following is the method I am using: Carrier gas: Helium Carrier gas flow rate: 1 mL/min (constant flow) Injection volume: 1 μL Injection port temperature: 250 °C Split injection ratio: 30:1 Initial oven temperature…
The degasser in our G7112B failed (diaphragm in the vacuum pump tore) and I swapped it out with a spare G1311A/G1379 combo while we wait for parts/repair.
Everything is connected and configured properly, the instrument config in OpenLab CDS 2.3 has…
Hello, The tune evaluation on the 5977B GC-MS is failing. The reason is 502/69 mass ratio is smaller than 2.4 (reading = 1.5-2.0), more specifically the 502 m/z count is around 7000-9000, instead of 20000 which is seen in previous autotunes. I cleaned…
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…
How long is your "electricity problem" ? And what is it? A switchover or a full-on power fail or?
Agilent does not support GC or GCMS on a UPS as too many UPS cannot handle the high amperage load. See: (+) Use of a UPS to Supply Power to an Agilent…
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…
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…
Rapid through-barrier raw material identification
Point. Click. Get a pass or fail result.
It almost seems like magic at first, a workflow so simple it begs the question, why do it any other way? Through-barrier raw material identification is an absolute…
