Definitions:

M/Z 127

The mass-to-charge ratio of an ion with a mass of 127 atomic mass units and a charge of one.

M/Z Fragments

In mass spectrometry, these fragments are pieces of a molecule resulting from ionization and fragmentation, described by their mass-to-charge ratio.

MS Peak

Refers to a peak observed in a mass spectrum, representing a particular ion's mass-to-charge ratio.

M+2 Peak

A term used in mass spectrometry to describe the peak that appears two mass units above the molecular ion peak, often indicating the presence of elements like chlorine or bromine.
