Refractive index detector RID-20A

differentialdynamiclaboratory

Overview
Based on the Prominence series' stability and extensibility, the RID-20A is a high-sensitivity differential refractive index detector featuring a reference-cell auto-purge and a validation support function for regulated environments.

Key features

• Reduced stabilization time and improved baseline stability: dual-temperature control of the optical system shortens time to a stable baseline after power-on.
• Short warm-up time: the optical system is housed in a dual-temperature-controlled block with two-stage control of the incoming mobile phase.
• Wide dynamic range and high sensitivity: four-partition photodetector covers a refractive index range of 0.01 to 5000 μRIU, supporting analyses from highly sensitive to preparative.
• Reference-cell auto-purge and validation support function: automated purge and validation tools improve operation and traceability in regulated workflows.
