What isotope spacing contributes to a spectrum

Spacing among isotope-related signals contributes to interpreting a mass spectrum. It should be considered alongside charge assignment and the stated composition rather than used as a standalone identification rule.

For research use only. Not for human or veterinary use.

A reference diagram may show an expected pattern, while a certificate may report an observed one. Label the two clearly. If only an identity conclusion is supplied, do not create a synthetic spectrum and present it as measured data.

Reading checklist

Distinguish expected and observed signals
Retain the charge assignment
Never substitute a diagram for missing measured data
