I'm using MassHunter Quant 10.0. Under Library Search Reports - TIC Library Search Report is where I start for TIC analysis, which will open the unknown analysis software and then I can further modify. But I found out there are some issues when I processed the data.   1. The Dil. column under the unknown analysis always show as 1. The correct… (Show more)

In the newer version of openlabs whenever there is not a peak integrated in the mass signal, the report shows "no spectra available" like here below for the TIC scan. We would like to not show when there is not a peak, how can I adapt this to just showing nothing. I think an 'IF" function is needed… (Show more)

Dear Sirs,   1) How can I add more units in Qualitative Masshunter as I saw only three ones: ng/ml, pg/mL and ug/L. I am using MH version B.07.01/Build 7.1.524.0   2) How can I issue the report of % Ripple for gradient check of HPLC in Openlab   Thank you for your time.

Hi All, I'm quite new to custom calculations within openlab and am a bit stuck on a particular problem and was hoping someone would be able to help.   Is there a way to reference the Amount entered for a particular compound in the calibration table. I.e. instead of CurrentCalibrationCurve.Amount(1) it would be something like… (Show more)

Click to view contentIn our qual v.10 reports the mirror spectrum is scaled to the library spectrum, not the acquired spectrum. I can't find any settings in the report builder to change it so it sometimes gives a misleading spectrum if acquired fragments are below the lowest mass in the library spectrum. Does anybody know how to change the scaling to be against the… (Show more)
