How does it work?

The measurement of refractive index, also called the index of refraction, is a straightforward process when using modern instruments. Nevertheless the generation of accurate and reproducible results demands that appropriate techniques are used and laboratory technicians are adequately trained. One major advantage of a modern digital refractometer is that sample preparation is no longer necessary.

Liquid samples can simply be placed on the measuring prism and the analysis begun. Good practice requires that the calibration of the instrument is regularly checked, and this can be done by simply measuring the refractive index of a sample of distilled water. One factor that must be considered is temperature: the refractive index of a substance varies with temperature, and so this must be carefully controlled. A digital refractometer will either incorporate a Peltier temperature control element or, in the case of less advanced instruments, a water bath controlled by thermostat.
