Abstract

Sample concentrating chromatography is a technique designed for trace analysis of organic compounds without the conventional concentration procedures such as nitrogen blowing or vacuum distillation. This method is uniquely suited for quantification of single insect pheromone production. Depending on temperature, gypsy moth females produced from 2.4 to 4.0 μg of sex pheromone (7,8-epoxy-2-methyloctadecane) per day.

Résumé

Il y a une méthode de chromatographie pour analyser les petites quantités de substances organiques sans utilizer des procédures ordinaires, par example, evaporation de dissolvant ou distillation à vide. Cette méthode est uniquement convenable pour le quantification de la production de pheromone d'un seul insecte. Dépendant de la température, les femelles de Lymantria dispar produisent de 2.4 μg à 4.0 μg pheromone sexuelle (7,8-epoxy-2-methyloctadecane) par jour.
