The NEW Differential Refractive Index Detector for HPLC, GPC/SEC
The new Refractive Index Detector RI 2012 series provides a consistent enhancement of the already successfully established Refractive Index Detector models RI 2000 and RI 2000-F.
The Refractive Index Detector RI 2012 series offers users 3 times higher sensitivity, (compared to RI 2000) stability and reproducibility required for optimal refractive index detection in HPLC and GPC/SEC
The new Refractive Index Detector RI 2012 series provide autopurge and autozero capabilities, as well as RS-232 and USB communication to acquire data directly without using any external signal interface.
Refractive Index Detector RI 2012 detectors are available for:
- micro
- analytical
- semipreparative mode
