If you have ions in negative polarity and no ions in positive polarity, this means that one of the switching power supplies has failed. You'll need a trained engineer to identify & replace the part.
On that model, the vacuum system must reach a certain level, to start the turbo pump. So, in your case, it could be the thermocouple is burned out, or the backing pump is not working, or the turbo controller has failed. If you have the capability, check…
Dear Mike, thank you for your assistance. After reinstalling the cables and powering the system, the initialization of the instrument fails with all kinds of errors: 9:9614NMP:E9614 8031 timeout 9:9604NMP:E9604 Microm datum 9:9328SEQ:E9328 fatal initialisation…
yeh sure. Using the expression box, I want the ISTDPeak ISTDReponsePercentDeviation. I can get it from the Field Value options but I want to get it in an expression then I can apply a function like: "Pass" if BoundItems["ISTDPeak"].ISTDReponsePercentDeviation…
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…
The model number on GC is 6890N (G 1540N). I am using a method with split injection with 50:1 split ratio on hp-5 column to measure concentration of a methanol/water mixture using ipa as an internal standard. The method has been successfully used giving…
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…

Hi I am facing problem with 6420A where it was not communicating and giving MSQQQ driver error. we replaced the quad driver and it started communicating. and fater quad dip when we started for tune we where not getting any response. Lab advisor test attached…
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"…
