XAD resins have been used to collect and concentrate organic materials from seawater. They can also be used as packings for fractionation by column chromatography. While they have been used in simple gravity flow column chromatography, high pressure liquid chromatography has also been used [74-78]. 

Internal reflection spectroscopy is widely applied for on-line process control. In this type of application, the chemical reactor is equipped with an internal reflection probe or an IRE. The goal of this type of application is the quantification of reactant and/or product concentrations to provide real-time information about the conversion within the reactor. In comparison with other analytical methods such as gas chromatography, high-pressure liquid chromatography, mass spectrometry, and NMR spectroscopy, ATR spectroscopy is considerably faster and does not require withdrawal of sample, which can be detrimental for monitoring of labile compounds and for some other applications. 

Fish and Komlenic (1984) and Fish et al. (1984) employed size exclusion chromatography-high-pressure liquid chromatography (SEC-HPLC) with element detection to determine the molecular weight distribution of metal-bearing compounds in four heavy petroleums. The observed... 

High Pressure Liquid Chromatography High pressure liquid chromatography can be used as a screening procedure instead of radioimmunoassay, although it is less sensitive. Extract 10 ml of urine with 25 ml of methylene chloride, separate the solvent layer, and dry it over anhydrous sodium sulphate. Examine 10 al of the extract using a silica column (Zorbax SIL, 5 am) (System HT, p. 219). 

GC- and LC-MS (Fig. 2), although others have also used other techniques including Fourier transform infrared spectroscopy, thin layer chromatography, high-pressure liquid chromatography, and Raman spectroscopy. The major techniques as judged by current number of publications will be discussed below.

The capabilities of various analytical methods are reviewed, such as capillary gas chromatography, high pressure liquid chromatography, thin layer chromatography and low temperature luminescence spectrophotometry. A candidate list of high priority PAH/POM compounds, including some representative heterocyclic compounds, which is based on occurrence in environmental emissions, health effects and analytical considerations, is discussed.
