- 4.1: Overview of mass spectrometry
- A mass spectrometer creates charged particles (ions) from molecules. It then analyzes those ions to provide information about the molecular weight of the compound and its chemical structure. There are many types of mass spectrometers and sample introduction techniques which allow a wide range of analyses. This discussion will focus on mass spectrometry as it's used in the powerful and widely used method of coupling Gas Chromatography (GC) with Mass Spectrometry (MS).
- 4.2: Determing the formula of a fragment based on the mass of the Peak
- This page explains how to find the relative formula mass (relative molecular mass) of an organic compound from its mass spectrum. It also shows how high resolution mass spectra can be used to find the molecular formula for a compound.
- 4.3: The M+1 Peak
- This page explains how the M+1 peak in a mass spectrum can be used to estimate the number of carbon atoms in an organic compound.
