Includes bibliographical references (pages 22-26). "This report describes development of a large-sample extractor prototype (GLSE/SR) which has been designed to operate in an "environmentally friendly" manner. The prototype possesses on-line analytical solvent recovery capability and minimizes exposure of operating staff to solvent vapour. The prototype has been laboratory- and field- tested in the Niagara River Toxics Management Program (NRTMP) and shown to be analytically equivalent to the original GLSE prototype which has been used in this program since 1986. The system is designed around a "standard" (for Niagara River monitoring) processing rate of 35 mL/min to collect a time-integrated extract of 50 L of sample over a 24 h period"--Abstract.
