The objective of this presentation is to demonstrate the original device and procedure for fast gas chromatography-mass spectrometry (GC-MS) analysis of gaseous and liquid samples and to discuss its features and capabilities. The concept was developed in order to expand the range of compounds suitable for GC separation and to reduce the time of analysis. Field GC-MS, consisting of original "concentrator-thermodesorber" (CTD) unit, multiple module GC system and compact magnetic mass spectrometer with powerful two-stage vacuum system and multicollector ion detector, is represented. The whole weight of the device is 90 kg. Power consumption is 250 W. The device and analytical procedures allow high speed screening of toxic substances in air and extracts within 100 s per sample. The examples of applications are described, including fast screening of tributyl phosphate (TBP) in air at low ppt level at the rate 1 sample/min.
本报告的目的是展示用于气态和液态样品快速气相色谱 - 质谱（GC - MS）分析的原始设备和程序，并讨论其特点和功能。开发这一概念是为了扩大适用于气相色谱分离的化合物范围并缩短分析时间。展示了现场GC - MS，它由原始的“浓缩器 - 热解吸器”（CTD）单元、多模块气相色谱系统以及带有强大两级真空系统和多收集器离子检测器的紧凑型磁质谱仪组成。该设备总重90千克，功耗250瓦。该设备和分析程序能够在每个样品100秒内对空气和提取物中的有毒物质进行高速筛查。文中描述了应用实例，包括以每分钟1个样品的速度对空气中低ppt水平的磷酸三丁酯（TBP）进行快速筛查。
