Dynamic range of a detector

Dynamic range (of a detector) The range over which the addition of further analyte brings about an increase, however small, in detector response. 

The linearity of most detectors deteriorates at high concentrations and thus the linear dynamic range of a detector will always be less than the dynamic range. The symbol for the linear dynamic range is usually taken as (D r) and might be specified in the following form for the FID as an example... 

Linear Dynamic Range - (D ) - The linear dynamic range of a detector is that concentration range over which the detector response is linear within defined response index limits. It is also dimensionless and is taken as the ratio of the concentration at which the response index falls outside its defined limits, to the minimum detectable concentration or sensitivity. The linear dynamic range is important when the components of a mixture being analyzed cover a wide concentration range. 

The linearity of most detectors deteriorates at high concentrations and, thus, the linear dynamic range of a detector will always be less than its dynamic range. 

The linear dynamic range (DJ of a detector is that range of solute concentration over which the numerical value of the response index falls within defined limits. For example, the linear dynamic range of a detector such as the FID might be specified as... 

The dynamic range of a detector (D ), is that range over which the detector continues to respond to changes in solute concentration and is not the same as its linear dynamic range. The dynamic range may extend from 1 x lO to 1 x lO g/ml. The use of a detector outside its linear... 

As a result of the electronic compensation of the background conductivity, the full dynamic range of a detector of this type is retained. Today, ion-... 

Section 12.2.6.1), In reality, deviations from linearity usually occur at high concentrations (saturation effect). An easy way to determine the linear dynamic range of a detector is to plot the signal-to-concentration (or sample size) ratio versus the logarithm of concentration (sample size) (see Fig. 8),... 

The linear dynamic range of a detector is that range of solute concentration over which the response of the detector is linear. 

The linear dynamic range of a detector is not the same as its dynamic range, as already stated, because the linearity of most detectors deteriorates at high concentrations of solute and in some instances, also at very low concentrations of solute. The linear dynamic range of a detector is also quoted in orders of magnitude of concentration and is given the symbol Dl e.g.
