PL-ELS 2100 Evaporative Light Scattering Detector (ELSD) features the PL-ELS 2100 Ice (Integrated Cooled Evaporator), which operates at temperatures down to 10 C. The detector applies a stream of dry nitrogen during the evaporation step to reduce the relative humidity of the surroundings. The addition of evaporation gas not only allows low temperature operation with aqueous mobile phases but also facilitates the removal of water at sub-ambient temperatures.
