WebApr 10, 2024 · High-resolution analysis using GC-QTOF-MS resulted in the spectrum below for the unknown. N-Nitroso-diisopropylamine as a potential identification was ruled out based on the 130.0862 m/z ion corresponding to C6H12NO2+ rather than the molecular formula of N-Nitroso-diisopropylamine (C6H14N2O).

WebHigh Resolution Mass Spectrometry. In assigning mass values to atoms and molecules, we have assumed integral values for isotopic masses. However, accurate measurements show that this is not strictly true. Because the strong nuclear forces that bind the components of an atomic nucleus together vary, ... WebHigh mass accuracy is not sufficient if mixtures are analyzed or if the isotopic fine structure of compounds needs to be evaluated. In such a case high resolving power is needed. High resolving power can be achieved by chromatography or comprehensive chromatography (GCxGC, LCxLC) or multidimensional chromatography (LCxGC).
