Abstract
Refractometer comprises a light source which directs a light beam through a measurement zone to a detector. Movement of the beam in a measurement direction w.r.t. the detector indicates the measurement made in the zone. The position of the beam w.r.t. the zone is modulated through a preselected amplitude which is independent of light beam movements at the light source or between the source and the modulating device to render the measurement independent of beam movements in the modulation direction. Used for measuring changes in the refractivity of a flowing fluid in liq. chromatography.
