See more information per run

The ACQUITY UPLC ELS Detector enables users to see more information per chromatographic run. Evaporative light scattering technology allows the monitoring of compounds that do not have a UV/Vis response and do not ionize well in mass spectrometry. This innovative detector can, therefore, efficiently supplement other detectors.


Achieve ultimate flexibility with multiple detector options

A suite of detectors for samples where some of the components lack chromophores or do not ionize well by mass spectrometry is key to the success of your laboratory.

The ACQUITY UPLC ELS Detector has precise temperature control for the nebulization and desolvation process to cover the entire ACQUITY UPLC PLUS series flow rate range, conveniently allowing you to run samples under different conditions. The detector also provides a snap-in self-aligning lamp and nebulizer for easy serviceability. 


Resolution, sensitivity, and speed designed to suit your needs

Monitoring product batches and carrying quality control of finished goods is intrinsic in pharmaceutical and chemical analysis laboratories. The ACQUITY UPLC PLUS series line of products is critical for the resolution, sensitivity, and speed required in such environments.
