Abstract
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.
Claims11
A device for evaporative light scattering detection wherein a sample to be detected is flowed through the device, the device being capable of easy conversion between a single flow configuration and a split flow configuration, the device comprising:
- a nebulizer;
- a drift tube in flow communication with the nebulizer, the drift tube comprising a drain outlet and a retractable impactor positioned downstream in the direction of flow from the nebulizer;
- a light source positioned downstream of the drift tube;
- and
- a detector.
