METHOD AND SYSTEM FOR PROVIDING A MODIFIER TO A CURTAIN GAS FOR A DIFFERENTIAL MOBILITY SPECTROMETER |
摘要 |
A system including a differential mobility spectrometer is described as is a method of operating the system including the differential mobility spectrometer. The method and system involve a) providing ions to the differential mobility spectrometer; b) providing a drift gas to an inlet of the differential mobility spectrometer; c) adjusting a meter to define a selected volumetric flow rate for supplying a modifier liquid to the drift gas; and, d) supplying an actual volumetric flow rate of the modifier liquid to the drift gas, wherein the actual volumetric flow rate is within a percentage deviation from the selected volumetric flow rate |
