The Sykam S 3585 Refractive Index Detector with programmable flow cell temperature control, thermal isolated optics and a choice of a micro, analytical or semi-preparative flow cell makes the S 3585 RI Detector the universal choice for applications requiring highly stable and sensitive refractive index detection.
Description
The Sykam S 3585 RI Detector is the ideal Refractive Index Detector for a multitude of system configurations. With the the micro flow cell (up to 3.0 ml/min), analytical flow cell (up to 10 ml/min) or semi-preparative flow cell (up to 50 ml/min) and measuring ranges of up to 500 µRIU, 1000 µRIU and 20000 µRIU respectively, the detector offers highest sensitivity for microbore HPLC and highest dynamic measuring range for preparative applications. Along with the comprehensive connectivity – analog as well as digital – the S3585 RI Detector can be applied in virtually any chromatography system requiring refractive index detection.
