 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.
