Definitions:

M+2 Peak

In mass spectrometry, this peak results from molecules containing two isotopes heavier than the most common isotopes (such as two chlorines), indicating the presence of elements like Sulfur or Chlorine.

MS Peak

A peak observed in a mass spectrum, representing ions of a specific mass-to-charge ratio.

Mass Spectrum

A graph or data set representing the distribution of ions by mass in a sample, used to determine the molecular weight and structure of compounds.

M/Z = 43

Represents the mass-to-charge ratio of 43 in mass spectrometry, indicative of a specific fragment's mass.
