Abstract:
1. A light scattering detection apparatus comprising: a nebulizer having a first inlet port for receiving chromatographic eluent with sample material and solvent, and a second inlet port for receiving nebulizing gas, said nebulizer producing primary aerosol of different size droplets from said eluent; a nebulization chamber coupled to said nebulizer for receiving the primary aerosol of different size droplets and nebulizing gas and for separating droplets of primary aerosol into larger and smaller sizes of droplets partially drying thereof, the droplets of smaller sizes and the nebulizing gas forming a secondary aerosol; and a drift tube having a first inlet port connected to the nebulization chamber for receiving the secondary aerosol, and a second inlet port for receiving an evaporator gas into the drift tube for mixing with the secondary aerosol, wherein the evaporator gas allows for drying of the secondary aerosol by evaporating a solvent from the droplets to form a tertiary aerosol of dried aerosol droplets.
