HPLC Detectors: Evaporative Light Scattering

New Features from SofTA Corporation

Jan. 16, 2004 --

Three Evaporative Light Scattering Detectors (ELSD) are introduced, each setting new standards for features and affordability. The Model 200 and 300 Evaporative Light Scattering Detectors (ELSD) feature continuously variable split ratio. Thermo-Split technology (patent pending) lets a user optimize the detector for mobile phase, flow rate, and analyte. The model 300 ELSD features full color touch screen display, built in data acquisition, and a USB hub that allows hook up to a printer, keyboard, mouse, and extra data storage. The Model 100 combines simple operation and great sensitivity.

Evaporative light scattering detectors are near universal detectors, primarily used in High Performance Liquid Chromatography (HPLC). ELSD’s are replacing ultraviolet (UV) detection because they can detect most analytes, even those that do not absorb UV radiation, are stable during gradient elutions, and respond to the relative mass of the analyte -a important feature that is useful when detecting unknown materials. The ELSD is superior to the refractive index detector (RID) it can be used with gradient chromatography, it is not susceptible to ambient temperature changes, and it does not produce negative peaks, which can be difficult to quantify. The operation requirements of Mass spectrometry (MS) detection closely match that of the ELSD. This allows the less expensive and complicated ELSD to be used as a method development detector for methods to be used on the MS systems.

SofTA Corporation will display the ELSD in booth #4057 at the 2004 Pittsburgh Conference in Chicago.
