The VERITY® 1601 ELS Detector is an evaporative light scattering detector (ELSD). An ELSD is not dependent on UV absorbance and can detect compounds or impurities even if they do not contain chromophores, making it an ideal complementary detector to a UV-based purification system. With the use of Conditional Logic Fraction Collection in TRILUTION® LC and GLIDER Software, the VERITY 1601 ELSD can ensure pure fractions by detecting and separating impurities that are not seen by other detection methods.
• Detect any analytes with and without chromophore groups that are less volatile than the eluent
• Compatible with LC gradient solvent system
• Compatible with most LC solvents whatever their absorption characteristics
• Provide a very stable baseline that improves the fraction collection triggering
• Low-temperature evaporation allows detection of semi-volatile or thermally labile compounds
• The nebulization chamber has been specially designed to work with highly concentrated eluents frequent in preparative separations by HPLC or Centrifugal Partition Chromatography (CPC)
