3 terms and units of measure
3.1 Resolution
The ability to resolve two adjacent mass spectral peaks, for a benchtop GC-MS with a peak width at 50% of an ion peak height
(abbreviated as half-width), denoted as W1/2, unit u.
3.2 Baseline noise (baselinenoise)
The width between the baseline peak and the valley, in units.
3.3 signal-to-noise ratio (signal-to-noiseratio)
The ratio of the signal intensity of the sample to be tested to the baseline noise is recorded as S/N.
3.4 Mass chromatogram (masschromatogram)
The mass spectrometer automatically repeats the scanning of the mass spectrometry data obtained within a certain mass range, and can be reproduced in different forms.
A spectrum in which one or more ionic strengths change with time is called a mass chromatogram.
3.5 Quality Accuracy (massaccuracy)
The deviation of the measured value of the instrument from the theoretical value.
3.6 u (atomicmassunit)
Atomic mass unit.
