dynamic range

of an analyser
The ratio between the maximum usable indication and the minimum usable indication (@D01628@). A distinction may be made between the linear dynamic range, where the response is directly proportional to concentration, and the dynamic range where the response may be non-linear, especially at higher concentrations.
