The Separation of Ions and Recording of Mass Spectra

There are many methods available for the separation of ions and recording of mass spectra. The ionization methods described above have been incorporated into all of the current commercial types of mass spectrometer. In this section only brief descriptions of these are offered. For a more complete discussion see either Chapman (1993) or Johnstone and Rose (1996).

The key parameters to take into account in the selection of a particular type of mass spectrometer for a GC-MS experiment are the masses of the compounds under consideration and the selectivity and sensitivity required for the analysis. Where the largest compounds to be encountered are likely to have a relative molecular mass of less than 1000 any of the types of mass spectrometer described below is useful.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
