Refractive Index Detector

RID-10A

Improving Analysis Productivity in Refractive Index Detection
The RID-10A features dramatic improvements in the productivity of refractive index
detection. Dual-temperature control of the optical system helps reduce the stabilization
time and baseline drift after power-ON, and the adoption of three measurement modes
allows all applications from high-sensitivity analysis to preparative work to be handled with
a single unit.

Aluminum Short Warm-up Time and Improved Baseline Stability
Optics block
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

insulators significantly shorter than with conventional systems. This dual-temperature control also helps
significantly reduce baseline drift, thus increasing the reliability of analysis data.

changed electrically. In A mode (for high-sensitivity analysis), the partitions are
0.01 grouped left-right (combinations of A+C and B+D), and in P and L modes (for preparative
analysis), the partitions are grouped top-bottom (combinations of A+B and C+D). In P and L

Option: Pressure Relief Valve (228-33615-91)
The RID-10A incorporates various safety features. Its maximum pressure is five times that of former Shimadzu products and, as a standard
feature, it incorporates a sensor that detects leakage from the cell unit. For extra safety, a pressure relief valve that prevents problems
related to back-pressure irregularities is also available as an option.
