Dear All! A customer would like to do the following (I already advised them about blank subtraction but it is not what they want): How to deduct blank peak area from sample (or standard) peak area What the customer has already done: CC1: to get the blank…
We have Thermo Xcalibur 2.2 to control both Agilent LC1200 stack and Thermo TSQ quantum Ultra, but Xcalibur could not recognize Agilent LC although it can see TSQ MS. it always says " pump/autosampler report a failure when trying to run initialize command…
I have a G1315C detector that fails "Lowest Intensity Test" in the 190-220 nm range (1867 counts) and the 221-350 nm range (4915 counts). All other intensity values are significantly lower than when conducted a year ago. A new Agilent lamp is installed…
Hello, I added tags to this post to increase visibility. It looks like this is a continuation of your previous post: https://community.agilent.com/message/4851-re-automatic-upload-failed-reason-unknown-error#comment-4851 . Is that correct? Typically we…
Hi.
From a year till now, every time we measure, whether in LA-ICP-MS or in liquid mode, sensitivity is not good.
Furthermore, relationship between masses differ a lot through time (like, 3 or 4 hours).
Agilent Argentina does not provide useful…
Hi Marty, Thanks for your reply and suggested CC approach. I will try to clarify what i want the report to do. i have attached an excel file showing an example but it doesn't open properly for me so i have inserted the table below. I want to report the…
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…
Hello Renato, Those tests would normally be completed by the Field Service Engineer as part of Operational Qualification for the instrumentation. The engineer has special software tools that enable automated testing and automated Pass/Fail assignment…
Hello
I am not an applications expert, but if I had to guess it is because ArC would be present through your calibration - from blank to all standards. ArC present in no gas mode would artificially increases counts in blank and standards, thus potentially…
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…
