Did the EM get replaced March 15? Or a source cleaning? The EMV went down 883V.
The Ent Lens (Entrance Lens) those jumps from 16 to 63,32,47.5 .. and the Ion Focus going from 80's to 40's... make me jumpy. Something was changing. When were source cleanings…
The ID testing process in the pharmaceutical industry often exposes warehouse staff to hazardous materials. This new technical note shows how pharmaceutical manufacturing QA/QC organizations can use the Agilent Vaya Raman system to check raw materials…
Hello,
You would need to do a custom calculation to get that result. See the example below. I show 2 ways to do the total area calculation. The first is using the peak status as a time reference the other is by the compound name.
By Is time reference…
My question is for Mr. Ken and the community (if you're confident in your answer): Regarding the ASTM Enhanced Mechanical Calibration for Dissolution apparatus, while the USFDA clearly recommends this method as an alternative to the traditional USP PVT…
Hello community,
I have the following error (attached images) when start either offline or online mode. As you can see, the module control panel also dissappear. I have checked all the conections between PC and all modules and the error window continue…
Hello everyone, I am writing to this forum because I have a problem with an LC-MS, specifically with a FlexCube module. The equipment is a 6410 and the Flexi module model is a G4227A 1290 FlexCube, which has 2 SPE online cartridges. The problem is that…
Good afternoon. Please help me find processing manuals for 6125, 6135 or any other models of mass spectrometers from the ESI ionization source to APCI. There is no information on the Internet. I have a ready-made source G 1947B APCI, a power supply and…

Recommendations updated after looking at this version from February 16, 2023. The recommendations are pretty much the same as above.
Increase the oven temperature equilibration time to 1.0 to 1.5 minutes or longer. It takes time for the 240° oven post…
We attempted the same testing on another OL2 instrument and the sensitivity issue was not present. It was unique to a single system. Agilent was very helpful getting us another system to test on. It seemed to be related to the tune/threshold/filtering…
