RI-4030/4035 Refractive Index Detector

The Refractive Index detectors include the optical system mounted in a precisely temperature-regulated housing to eliminate the influence of changes in ambient temperature. The RI-4030 and 4035 detectors are fully stable just one hour after powering on.

The RI-4030 can be used for both analytical and preparative scales. In preparative mode the maximum flow rate is 120 ml/min.

The RI-4035 is a dedicated semi-micro RI detector with a micro-volume flow cell designed for use with semi-micro GPC analysis using GPC columns with a fine pore size. The 100 Hz data acquisition rate makes the RI-4035 suitable for RHPLC and UHPLC separations.

The LED light source in both detectors has a long life time (over 10,000 hours) for low maintenance operation. Both the RI-4030 and RI-4035 detectors can be fitted with an optional pressure release safety-valve to prevent damage to the flow cell in the event blockage.
