Description: JASCO RI-2031 Plus Refractive Index Chromatography detector in working condition. See video for startup sequence and checkup. JASCO Model RI-2031 Refractive Index Detector Specifications Highly Reliable OpticsBased on Snell's Law of Refraction, utilizing a prism flow cell with sample and reference cells forming liquid prisms.The light beam is directed through a collimator lens, passing through both cells, reflecting off a plane mirror, then focusing on a photodiode.The difference in refractive indices is measured and converted into electrical signals. Advanced ElectronicsAnalog signals from the photodiode are converted to digital signals.The CPU computes the difference in refractive indices with compensation for light source fluctuations.The result is displayed on an LCD screen and sent to analog output via a D/A converter. High StabilityDesigned with a rugged optical bench and precise temperature control to ensure long-term stability.Maximum flow rate of 50 mL/min with a wide dynamic range. Time Programming CapabilityThe on-board microprocessor allows time-programmed changes in detector settings for unattended solvent replacement and peak detection optimization. Measurement SystemDeflection type, with a refractive index range from 1.00 to 1.75 RIU.Measurement ranges vary from 1/4 to 512 x 10⁻⁶ RIU for standard measurement and up to 512 x 10⁻⁵ RIU for wide range. SpecificationsLinearity: 5.0 x 10⁻⁴ RIU (standard) and 5.0 x 10⁻³ RIU (wide).Noise: Less than 0.20 x 10⁻⁸ RIU.Cell capacity: 10 µL.Maximum usable flow rate: 50 mL/min.Temperature control with PID, ranging from 0-40°C.Zero adjustment functions: Optical and electronic auto-zero.
