Hey everyone,
I'm looking for some help regarding some communication issues we're experience on the QQQ 6470 after starting it up. Upon starting the QQQ up after a temporary shut down, we are now having troubles with initializing communication and unable…
Is the tutorial available for the " Cary WinUV (Pharma) software complements the Cary 60 UV-Vis spectrophotometer" software? Could we use the WinUV 5.3 Tutorial for the WinUV 5.1.3 software where the tutorial does not work for us because it's written…
Hello, Jorge! Have you ever try to change gain? Go to Gain Adjust e try to put close to 25000. If it still continue red, try to purge your IR with nitrogen gas. If you prefer to speak in pt-br send me a mensager.
Sudhini , increasing the Electron Multiplier Voltage (EMV) will increase the detector response for all analytes.
Depending on the m/z of your impurity vs what you are filtering on in the MRM, your impurity may not be detected as it would need to have…
Thank you Ron,
I tried some templates, and it seems like the one called "Gen_LIMs_xmlOutput" already includes everything. Now my only problem is the custom calculation regarding Question 5 listed above. I will look in it.
Thank you again for your…
Hello dimei ,
In qual it is not easy to combine the compound results, which contain the compound name and RI, along with the peak list results, which contains the Area Sum Percent. The closest you can get in qual is the compound summary CSV export option…
I was able to figure it out on my own. Here is the code for anyone in the future who needs to solve this same issue:
peak = None if cmpd.IsPrimaryHitPeakIDNull() else DataProvider.GetPeak(istd.BatchID, istd.SampleID, cmpd.CompoundID, cmpd.PrimaryHitPeakID…
