Abstract
The present invention is directed to a system for converting between single flow and split flow evaporative light scattering detection devices for detecting samples in a mobile phase. Included in the system is a evaporative light scattering detection device, a low temperature adaptor, and a connection tube for providing a fluid connection between the evaporative light scattering detection device and the low temperature adaptor.
Claims9
A method for quickly converting from a single-flow configuration to a split-flow configuration of evaporative light scattering detection thereby providing increased ability to detect different sample types in different mobile phases, the method comprising:
- providing an evaporative light scattering detection device in the single-flow configuration comprising a nebulizer in fluid communication with one end of a drift tube, a light source and a detector;
- and
- converting to a split-flow configuration by removing the nebulizer and connecting a low temperature adaptor such that the low temperature adaptor is in fluid communication with the drift tube,
- the low temperature adapter comprising a low temperature adapter nebulizer, a nebulization chamber in fluid communication with the low temperature adapter nebulizer and the drift tube, wherein in the nebulization chamber at least a portion of a mobile phase carrying sample components is evaporated and a portion of the mobile phase is not evaporated, the nebulization chamber further comprising a sink trap in fluid communication with the nebulization chamber for removing mobile phase that is not evaporated in the nebulization chamber.
