This difficulty is overcome in refractometers by the use of monochromatic radiation. Views Read Edit View history. The effect is most pronounced in gases, where the change in n amounts to about 3x10 -4 per atmosphere; the figure is less by a factor of 10 for liquids, and it is yet smaller for solids. Refractive index of a substance is a function of a wavelength.

Measure samples as small as 1 ml, in the field with laboratory accuracy. I forgot my password! Therefore, it is an indispensability equipment in common use in. From Wikipedia, the free encyclopedia.
Amici prism for compensation of dispersion by sample. Temperature control of the prisms is achieved using water, the included thermostat and flexible piping. This bench-top Abbe refractometer can be used to determine refractive indexes in a temperature range from These instruments use special filters to reach the desired wavelengthand can extend measurements well into the near infrared though a special viewer is tefractometer to see the infrared rays.
They did, however, have the ability to electronically compensate for the temperature differences of many fluids where there is a known concentration-to-refractive-index conversion. Abbe Refractometer Get Quote.
