Abstract

An inexpensive, silent, maintenance-free suction/adsorption system is described for efficiently collecting submicrogram quantities of odors over a wide range of volatilities under field conditions. The samples can later be submitted to gas chromatographic-mass spectrometric analyses. An example is given with odors sampled from solitary bees engaged in digging and defensive behaviors at their nesting sites. Gas chromatograms of odor samples collected from known concentrations of synthetic chemicals are provided for standardization.

摘要

一种廉价、无声、免维护的抽吸/吸附系统，用于在现场条件下高效采集广范围内挥发性物质的亚微克级气味。这些样品随后可以提交进行气相色谱-质谱分析。以在筑巢地进行挖掘和防御行为的独居蜜蜂的气味为例。还提供了从已知浓度的合成化学品中收集的气味样品的气相色谱图，以进行标准化。
