In handling worldwide industrial hygiene problems for the Air Force, our Laboratory receives a heavy work load of charcoal tube and vapor monitor air samples. With our work load increasing, and more methods being applied to gas chromatography, any method which would remove some of the work load from our overworked gas chromatographs would be welcomed.

Frequently industrial hygiene analyses require the identification of unknown sample components. One of the most widely employed methods for this purpose is coupled gas chromatography/ mass spectrometry (GC/MS). With respect to interface with mass spectrometry, HPLC presently suffers a disadvantage in comparison to GC because instrumentation for routine application of HPLC/MS techniques is not available in many analytical chemistry laboratories (3). It is, however, anticipated that HPLC/MS systems will be more readily available in the future ( 5, 6, 1, 8). HPLC will then become an even more powerful analytical tool for use in occupational health chemistry. It is also important to note that conventional HPLC is presently adaptable to effective compound identification procedures other than direct mass spectrometry interface. These include relatively simple procedures for the recovery of sample components from column eluate as well as stop-flow techniques. Following recovery, a separated sample component may be subjected to, for example, direct probe mass spectrometry infra-red (IR), ultraviolet (UV), and visible spectrophotometry and fluorescence spectroscopy. The stopped flow technique may be used to obtain a fluorescence or a UV absorbance spectrum of a particular component as it elutes from the column. Such spectra can frequently be used to determine specific properties of the component for assistance in compound identification (9). 

Environmental analysis is one of the most important fields of application of ion chromatography it is divided into water hygiene, soil hygiene, and air hygiene.

The sulfide ISE is sensitive, reliable, and useful especially in analyses of the atmosphere and waters. The nitrate ISE does not exhibit particularly good analytical properties, but it enables very fast and simple ori-entative determinations of nitrate in, e.g., waters, vegetables, and foodstuffs, which is welcome with regard to public hygiene. ISEs for various inorganic anions have somewhat lost their importance in competition with ion chromatography and those for inorganic cations often cannot compete with spectral methods nevertheless, ISEs for copper(II), lead(II), and cadmium(II) ions are sometimes useful for endpoint detection in complexometric titrations.
