Summary:An improved evaporative light scattering detector apparatus for volatile samples is provided. Conventionally incomplete evaporation of the mobile phase (solvent) cannot be achieved for volatile samples as solvent cannot be fully removed at low temperature because the vapor becomes saturated. At higher temperatures the samples evaporate without forming an aerosol. By adding a dry evaporator gas to the sample before entering a drift tube avoids saturation of the vapor and permits complete evaporation of the solvent at low temperatures.
