Inheriting the stability and extensibility that are the strengths of the Prominence series, the RID-20A model of differential refractive index detector is designed with a new reference-cell auto-purge feature and validation support function. The optical system is housed inside a dual-temperature-controlled block. The temperature of the incoming mobile phase is controlled in two stages; consequently, the stabilization time is significantly shorter than with conventional systems. This dual-temperature control also helps significantly reduce baseline drift, thus increasing the reliability of analysis data. The single detector supports all applications from highly sensitive measurements to preparative measurements using the three operation modes.
