	Title	Bestimmung der relativen Flüchtigkeit von Sexualpheromonen von Schmetterlingen mittels Closed Loop Stripping* Determination of Relative Volatility of Lepidoptera Sex Pheromones by Closed Loop Stripping
	Abstract	By means o f closed loop Stripping the relative evaporation rates o f monounsaturated C U)-C\|6-acetates and C l(l-C12-alcohols have been determined. The results o f stimulus released demonstrate the different volatilities of pheromone compounds which should be taken in ac count with certain biotests and physiological studies.

	Title	GC Profiles of Volatile Constituents from Human Urine Obtained by Closed Loop Stripping, Purge and Trap Technique and Simultaneous Steam Distillation-Extraction
	Abstract	Different techniques like "closed loop stripping" [CLSA], "purge and trap" [PTI], and continous steam distillation extraction [SDE] were used to establish GC profiles of major histocompatibility com plex-associated volatile constituents of human urine and statistically evaluated for reliability. O f the three methods investigated, PTI appeared to be superior for the detection of very volatile substances, whereas SDE was the most efficient one with re spect to yield. A number o f short to medium-chain ketones, 4-hydroxy-3-methoxy-styrene, menthol and nicotine were identified in preliminary analyses.
