Mass Spectrometric Detectors for Environmental Studies
AbstractMass spectrometric detectors coupled with different separation techniques and employing various ionization modes are commonly applied for the investigation of a large variety of organic compounds and their biotransformation processes in environmental and biological materials. Inductively coupled plasma mass spectrometry (ICP MS) technique is one most versatile tool for elemental quantification in a large variety of environmental samples. This chapter discusses potentials of various ionization methods of the widest applications in the analysis of environmental materials such as electron ionization, field ionization/field desorption, and fast atom bombardment. The sensitivity and selectivity of MS detection substantially depend on a kind of mass analyzer capable of the separation of ions of different mass-to-charge ratio and transmission of a sufficient number of ions to the detector yielding measurable ion currents. Quadrupole (Q), quadrupole ion trap (QIT), time of flight (TOF), and Fourier transform (FT) are the main commercially available mass analyzers.
