A diagram of the general front-view of a differential refractometer. A differential refractometer (DRI), or refractive index detector (RI or RID) is a detector that measures the refractive index of an analyte relative to the solvent.
The general detection scheme [13] involves: Pneumatic nebulization of mobile phase from the analytical column forming an aerosol. Aerosol conditioning to remove large droplets. Evaporation of solvent from the droplets to form dried particles. Particle charging using an ion jet formed via corona discharge.
ELSDs analyze solutes eluting out of the chromatographic column, both in LC and SFC. As the eluent exits the column's outlet into the detector inlet, it is mixed with an inert carrier gas (usually nitrogen) and forced through a nebulizer, which separates the liquid into fine aerosolized droplets. These droplets then pass into a heated drift ...

A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.

Fast protein liquid chromatography (FPLC) is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the mobile phase) and a porous solid (the stationary phase).
