refractive index detector

A refractive index detector is an instrument used in chromatography to sense solutes in a mobile phase. It works by comparing how light refracts through the pure mobile phase versus how it refracts through the column effluent. The degree of refraction is dependent on the liquid's nature or the solution's composition. This type of detector is a general detector, meaning it senses all solutes regardless of their identity. The refractive index itself is the ratio of the speed of radiation, like light, in one medium compared to another.1234
