Optilab® Refractive Index Detector, Wyatt Technology Corporation (CAT#: STEM-LE-2011-LC)

TheOptilab® Refractive Index Detector is designed for standard HPLC/GPC with 256 times the detection power and 50 times the dynamic range of every other RI detector.

Type:Refractive Index Detector
Sensitivity:± 0.002 RIU
Refractive Index Range:1.2 to 1.8
Light Source:658 nm ± 20 nm standard; other wavelengths available
Dimensions:(WxDxH) 36 x 60 x 17 cm
Cell Volume:7.4 µL
Wavelength(s):658 nm

Extraordinary dRI measurement range, -0.0047 - +0.0047 RIU (comparable to 25 mg/mL protein in PBS)
Highly sensitive, ±7.5 x 10-10 RIU across the whole measurement range
Measures solvent absolute refractive index, required for MALS calculations
Measures at the same wavelength as the MALS detector, for maximum accuracy in MALS calculations
Band broadening < 20 µL preserves SEC resolution
Temperature range 4°C - 65°C for proteins and polymers which require a wide range of temperatures
High-resolution, touch-screen front panel displays data graphs and diagnostics, even with the host computer turned off
