	固相微萃取(Solid-phase microextraction, SPME)技术作为一种新型样品前处理技术已经得到广泛应用，然而SPME装置在我国一直以来都依赖进口。近几年，国内实现了SPME探针的国产化。本文对比了同型号国产和进口SPME探针的探针本底、使用重复性、制备重复性和实际样品应用效果。结果表明，国产和进口SPME探针的探针本底相当，国产和进口SPME探针使用重复性和制备重复性RSD值均小于10%。分别使用国产和进口SPME探针对某干红葡萄酒风味物质和92#汽油挥发性物质进行顶空SPME-GC/MS分析，结果显示国产探针比进口探针能够检出更多色谱峰。通过对比结果表明，国产SPME探针的性能完全等同于或优于进口SPME探针，能够实现进口替代。<br />
Solid-phase microextraction (SPME) has been widely used as a new type of sample pretreatment technology. However, SPME devices have always relied on imports. In recent years, the domestic SPME device has been realized. This work compares the performances of the same type SPME fibers between domestic and imported, such as the fiber background, the use and preparation repeatability, and the actual sample application. The results showed that the fiber background was equivalent to domestic and imported SPME fibers, and the use reproducibility and preparation repeatability RSD values of domestic and imported SPME fibers were both less than 10%. The GC-MS results of headspace extraction of red wine flavor substances and 92# gasoline volatile substances using domestic and imported SPME fibers showed that using domestic fiber can detect more chromatographic peaks than using imported probes. By comparing the results, the performance of the domestic SPME fiber was completely equivalent to or better than the imported SPME fiber, which can achieve import substitution.
