Overview
The Waters 2414 RID delivers universal detection for solutes lacking UV absorbance by measuring subtle changes in refractive index as analytes elute from the HPLC column. Its LED-based optics and precision temperature control produce exceptionally stable baselines and high sensitivity across a wide dynamic range, making it ideal for carbohydrates, polymers, and small molecules. Offered AS-IS, this unit is suited to service centers or laboratories equipped to perform flow-cell leak checks, optical alignments, and calibration before analytical use.
