摘要
利用金属的居里点特性,将少量活性炭涂在φ0.5×90mm金属镍丝的一端,制成一种新颖的色谱采样工具。通过解吸率试验、重复性试验、线性试验、检测极限等的研究,以及对环境污染样、野外地质样和水仙花活花头香样等的采集分析,证明吸附丝具有灵敏度商、重复性好、线性范围宽和应用领域广且功能特殊的优点,具有广阔的应用前景。
A new GC sampling tool--adsorption wire was made of a few milligram active carbon adhered to one end of nickle wire (φ0. 5×90mm) ,based on the Gurie-Point property of metal. The desorption ratio, repeatability, linearity and detection limit of adsorption wire was studied. Environmental pollution sample, geologic sample and perfume components of flower on growing were collected and analysed. So the adsorption wire is of the advantages of high sensitivity, good repeatability, wide linear range, more applied field and special function. wide application is expected.
