Tutorial: Fundamentals of GC/MS
The following web pages are Flash based tutorials that outline the Fundamentals of GCMS. To learn more about Flash, you can visit the Adobe website.
A mass spectrometer is an instrument that measures the mass of microscopic particles such as molecules and atoms. We can identify a molecule and quantify the amount of target chemicals in mixtures from this information. Mass of natural materials and units of mass will be explained here.
- Mass of Materials
- Mass Number and Isotope
- Isotopic Abundance of Carbon Atoms
- Isotope Abundance Table
- Molecular Weight
Ionization produces positively- and negatively-charged atoms, mplecules, or fragments called ions. An overview of a mass spectrum will be provided and various types of ions will be introduced.
- Example of Mass Spectrum
- Base Peak
- Fragment Ion
- Isotope Peak
