Tutorial: Fundamentals of GC-MS
The following web pages tutorials that outline the Fundamentals of Gas Chromatography Mass Spectrometry (GC-MS).
What is Mass?
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.
Types of Ions
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.
