Abstract
The evaporative light scattering detector (ELSD) is a universal HPLC-detector with many applications for non-volatile constituents of foods. In contrast to the refractive index detector, the ELSD is compatible with gradient elution and, therefore, suitable for complex samples. The function of the detector and the effects of parameters, such as properties of the eluent, flow rates of carrier gas and eluent, evaporation temperature, and structure of the analyte on detector sensitivity are explained. For quantitative results, an optimization of the detection parameters and a precise calibration are necessary. Calibration curves are sigmoidal, and the linear range mostly extends to one or two orders of magnitude Relative standard deviations of around 1% can be obtained. Detection limits in the middle or upper ng-range are to be expected. Applications for the analysis of lipids, carbohydrates and other important classes of natural compounds are compiled.
