GC-MS (QQQ) June 05, 2020, 03:53:51 AM Dear Hiroshi, Dear Ms_dial user,Recently I tried to use MS-Dial to analyze GC-QQQ data (Standard of Fames), acquired by Thermo QQQ.Here I compare 2 Fames standards with 2 blank.I set the parameter "Minimum peak height" at 1E06. (see parameters_1.png)After the alignment I checked all the peaks.As expected, I note that in the blank, there is no peak C18: 3n6 (Peak Id :-2). (see Picture_2.png).Although the software automatically takes background noise for Blank, the peak heights are less than 1E06.Having set the parameter "Minimum peak height" at 1E06, I wonder why the blank value is not 0?Sebas Quote Selected
