Hi, when launching OpenLab Control Panel the connection to shared services fails. When I check the connection it shows that the problem is "Agilent OpenLAB Shared Services" service is not running. However Net.tcp port is enable and running. Any suggestion…
I want to load firmware the firmware of a 5975C Is there a way to manually load firmware onto a smartcard (instead of Agilent Configuration)? I have encounter an issue where someone has tried to update firmware using a computer that has various firewalls…

I spent the last couple days playing around with the ratios and I think I've succeeded! Thanks Ron! Here's what I ended up doing, for anyone else that might be trying the same thing. First, I will say these conditions only work with the 5 ppm DFTPP solution…
Hello camelia, I added tags to this post to increase visibility. One way to address this would be to set up a custom calculation to identify missing compounds for a given injection/signal. The below formula will output "No Calibrated Peak(s) Missing"…
Hello, For the Servo Restart Failed error, it can be created from the pump drive not moving properly. It can also be cause by a blockage of the Inlet valve or Outlet valve. So you can try to loosen one of them and start the module and see if it gives…
The drops in baseline were still present when we blocked off the MS with a no-hole ferrule. Cleaning the source seemed to resolve the baseline issue and tune. Thinking it must have oxidized to some extent when the vacuum pump failed.
Hey all, What is the primary difference between deuterium lamps 5182-1530 and 2140-0813? We recently replaced 5182-1530 with 2140-0813 on our 1100 HPLC but after the wavelength verification test, the lamp is failing the D2 alpha line deviation. Got 1…
Dissolution testing is labor intensive as well as a technique and time dependent analytical procedure. A typical dissolution workflow consists of several steps including dissolution media preparation, media filling, introducing the dosage form into the…
We have 6490A LCMS. Instrument works well but when I checked for autotune it failed. The data seems OK but now days I have to autotune every two weeks. Can anybody advise if I am over killing (by too many times autotuning) or it is a signal of instrument…
