Hello Can someone try to explain the following errors to me (and how to fix it)? manual integration failed... 1. "Object reference not set to an instance of an object" or/and 2. manually integrated peak does not match quantitation criteria also wondering…
We are about to add reaction gases to the Agilent 8900 ICP-MS reaction cell: NH3 and O2. Is the mechanical pump already sealed with Viton O-rings?
The equipment is for this application specifically, so I assume it does, but I would like to confirm this…
Dear ryoboyle, thank you for the quick response. I am creating an IR-template for reporting results of unknown impurities from multiplate injection of sample or/and from multiple preparation of one sample batch. I use „Compound_Name“ for grouping them…
Thanks, James. I ran into the "Autostart Macro failed, error# 17928 occurred" and then Chemstation opened up to the "Data Analysis" window. I switched the view to the "Method and Run Control" window, closed Chemstation and then reopened it. I did not…
Hi all
I have recently encountered a problem in my bfb.u tune file parameters..
All of the sudden, my 5973 won't pass bfb tune (*inconsistent peek width*) (pic 1) though it passes Atune ( pic 2) just fine..
Enclosed for reference are images…
We are struggling with an issue where our mobile phase will not *actually* change composition during a gradient when going from a more viscous solvent to a less viscous one (H2O to acetonitrile, for instance). The instrument says it should be changing…
To use A-PLUS you must connect your Agilent product to a PC with a USB port using a Moxa adapter. Moxa is adapter/converter requiring specific drivers to be installed on your PC. It's important to download and install the drivers for your Moxa adapter…
