Refractive Index (RI) Detector

$Refractive Index RI Detector$

The Refractive Index Detector with outstanding capabilities

This differential refractive index detector has the sensitivity, stability and reproducibility required for optimal RI detection.

The detector features a user programmable temperature control and thermally shielded optics with a countercurrent heat exchanger. This results in an extremely stable baseline and an optimal signal/noise ratio.

This RI detector offers remote purge and autozero capabilities. It also features a bi-directional RS232 connection for computer control.

Refractive index detectors are available for both analytical and preparative applications.
