Product catalog summary
Overview
The RI 2000 series of Differential Refractive Index Detectors are designed for high sensitivity, stability, and reproducibility in refractive index detection. Key features include a thermally isolated optic with a counter-current heat exchanger and programmable temperature control, ensuring a stable baseline and optimal signal-to-noise ratio. The detectors also offer autopurge, autozero capabilities, and RS232 communication for direct data acquisition.
