The present invention is directed to a device for evaporative light scattering detection that can be used for a wide range of sample types and mobile phases. The device may be quickly converted between a single flow and a split flow configuration through the use of a retractable impactor (105). The drift tube (104) of the device is in flow communication with the nebulizer (102) of the device, the drift tube (104) comprising a drain outlet (110) and the retractable impactor (105) positioned downstream in the direction of flow from the nebulizer (102).
