Mass spectrometry flow chart

The individual steps of the method are shown in the flow chart of Figure 1. Hydrocarbons are extracted from ocean water and measured by IR spectroscopy. Then the sample is placed on a silica gel column and hydrocarbons are eluted as a fraction(s) which is examined by IR and UV spectrometry, gas chromatography, and mass spectrometry. Each of the principal steps is described in the following sections. Some aspects of this method and typical applications were briefly described by Brown etal. (6).
