This paper presents a novel fast injection device on gas chromatograph. This thermal separa-tion probe provides a fast and reliable way to introduce sample into gas chromatograph or mass spectrome-ter. It’s perfectly compatible with current gas chromatograph inlets and performs a direct injection for ac-curate qualitative and quantitative result without complex extract and cleaning especially for difficult-to-va-porize samples such as solids and slurries. T his device enables on-site fast screening and analysis.%本文介绍了一种新型气相色谱质谱快速进样装置的设计。热解析进样器提供了可靠快速的气相色谱及质谱进样方式，与现有气相色谱进样口很好匹配，实现样品直接进样，无需对复杂样品特别是难挥发的样品如固体或粘稠状样品进行萃取及净化，即可获得准确的定性定量结果。这一方法使现场快速检测快速分析成为可能。
