SIFT-MS有两种不同的运行模式,一种是全扫描模式,即在一定m/z范围内得到通常的质谱图,用于鉴定前体、产物离子和他们相应的计数率,在线计算机立刻计算这些痕迹量气体在呼吸气中的分压,为此要有可鉴定的产物离子,而且它们还要包括在分析所需要的动力学数据库中,动力学数据库包括速率系数和前体离子/痕迹量气体化合物反应...
SIFT-MS relies on known ion-molecule rate coefficients to determine analyte concentrations. Mass-selected negatively charged reagent ions in SIFT-MS extend greatly the range of atmospheric pollutant molecules that can be monitored. The same real time response is available for negatively charged reagent...
SIFT-MS is a revolutionary direct mass spectrometric method for continuous, sensitive, selective, and fast real-time analysis of air down to ppbV and pptV levels, depending on the analyte. The SIFT-MS instrument from Syft Technologies is a unique monitoring apparatus that can measure volatile orga...
