WebMar 1, 2007 · The SIFT-MS technique uses a soft chemical ionization reaction between a single selected reagent ion and the gas-phase sample analytes that produce fixed chemical reactions. By using gas-phase ion chemistry and tightly controlled reaction conditions, SIFT-MS provides instantaneous quantification of target analyte species. WebSIFT-MS, the ion-molecule reactions inside the flow tube are well understood and occur at known reaction rates. Using these reaction rates, SIFT-MS is able to quantify compounds to an accuracy of ±25% without individual compound calibration. However, SIFT-MS is able to achieve a better accuracy (±5% rsd) by performing
