Differential Refractometer For Chromatography
Small or Large Amount of Samples, by YAMAZEN Technology

Differential Refractometer

Yamazen's RI-31 Differential Refractometer is an exceedingly sensitive and energy efficient detector with a high intensity LED lamp which emits target amount of light at lower voltage with a built-in adjustment of light. With the PS method, RI-31 has a wider dynamic range than the conventional type and NO saturation for highly concentrated samples.

  • Purification of samples from mg to dozen grams
  • Fast Stabilization of the baseline
  • Steady baseline even in chromatography of large flow rate (~100ml/min)
  • Applicable to organic solvents
