Hello everyone,
We have a problem with the acquisition methods on GC, but not on HPLC.
When we want to change an acquisition method that is in "approved" status to "generic" status in order to modify it, it is impossible to do so because the box is…
I found the issue. I have "Hide duplicates" selected which prevents any additional Fails from being displayed. However, if I uncheck that box, there is a Fail in every row. This is a summary result, is there a way to make it display only once per group…
Hello all,
I made a custom excel report template for GC-MS/FID data I'm working with in MassHunter B.10 and I'm having an issue getting the template to report the user selected "best" from the spectrum ID results list.
Here is how I've added the table…
I'm trying to create a report with a column which calculates the percentage of all integrated peaks above a specific threshold. I have created a report parameter to format the number of significant digits, this is a request of some of our clients. At…
Hi! Recently we baught GC 8890 with tandem detector fid-scd(detector for sulfor detection 8355). In this case limit of detection of sulfur compaunds is very high (ppm level). We need to meet more low limits of detection of sulfur compounds. Can we dismount…
Before first use: Soak in 100ppm sodium calibration standard for 24 hours to condition the probe With use (submersion in the liquids under test) the response time will become slow and it might be difficult to calibrate. If this occurs the probe needs…
Thanks for the response Matthais. The issue actually is that autotune sometimes fails to match EPA compliance criteria, and so it becomes necessary to manually tweak settings. I get that Agilent doesn't want lab techs carelessly messing around with quadrupole…
I am using MassHunter Qualitative Analysis B.07.00 to analyze FID data. I have extracted the FID chromatograms, identified the peaks and annotated them. But nothing happens when I try to print reports. Can anyone help me figure out how to generate the…

...
This Information Applies To: Agilent UV and RID detectors
Issue
A clogged flow cell causes high backpressure. The clog can be removed by flushing the system with solvents at high pressure. If you suspect a clog or experience high backpressure due...
This Information Applies To: Agilent G1312X and G7112X binary pumps.
Issue:
A blockage before the pressure sensor, e.g. in a pump head, will not give a high pressure or overpressure system error. Instead, the pump may show one of various error messages...
This Information Applies To: Agilent 1100, 1200, 1260 LC Pumps.
Issue:
