The discussion of the applications is prefaced by very brief descriptions of: 1) the resin characteristics, 2) the extraction device, 3) some efficiency tests, and 4) the general methodology. Recent developments of simple and inexpensive procedures for the monitoring of selected contaminants of concern are stressed. Examples are given of the contamination of water by PVC tubes and of the measurements of pesticides, amines, halocarbons, and model compounds in water. Practical comparisons of the resin sorption method to carbon sorption and solvent extraction procedures are presented and recently developed mini-samplers are discussed.

Organic pollutants in water are isolated on a mini-sampler tube containing a macroporous resin. The sorbed pollutants are next thermally transferred to a second sorption tube and then to an analytical column where they are separated and determined by temperature-programmed gas chromatography. Excellent recoveries were obtained for tests in which model organic compounds of various classes were added to water. The water sample is much smaller than that required with previous analytical methods.
