Waters 2424 ELS Detector

Waters 2424 ELS Detector

Cambridge ID #: 16585

The 2424 Evaporative Light Scattering (ELS) Detector is a compact detector that controls temperatures in both the nebulization and evaporation stages, maintaining low-dispersion characteristics for dependable HPLC/ELS results. It allows you to obtain more peak information per run and reliability and reproducibility for LC and LC/MS.


Use the detector as part of an Alliance® HPLC or LC/MS system under the direct control of either Empower or MassLynx Software, or as a stand-alone ELS module. This open access-ready detector integrates with the AutoPurification System for flexible, multi-detector purification and isolation solutions.


The 2424 ELS Detector provides solutions for the analysis and purification of a wide variety of compounds that lack UV/Vis chromophores including triglycerides, sugars and natural products.
