Topics - Dynamic Range

Dynamic Range In chromatography, the term dynamic range refers to the performance of the detector. There are two detector dynamic ranges, the dynamic range per se and the linear dynamic range. The dynamic range is that range of solute concentration over which the detector continues to respond to changes in solute concentration. It extends from the minimum detectable concentration to that concentration where the output no longer increases with increase in solute concentration. The linear dynamic range is that concentration over which the detector output is linearly related to the solute concentration. The linear dynamic range extends from the minimum detectable concentration to that concentration where the response index is greater or less than the defined linearity limits.
