Analytical Figures of Merit for Multisensor Arrays

Multisensor
arrays employing various sensing principles are a rapidly
developing field of research as they allow simple and inexpensive
quantification of various parameters in complex samples. Quantitative
analysis with such systems is based on multivariate regression techniques,
and deriving of traditional analytical figures of merit (e.g., sensitivity,
selectivity, limit of detection, and limit of quantitation) for such
systems is not obvious and straightforward. Nevertheless, it is absolutely
needed for further development of the multisensor research field and
for introducing these instruments into the general context of analytical
chemistry. Here, we report on the protocol for calculation of sensitivity,
selectivity, and detection limits for multisensor arrays. The results
are provided and discussed in detail for several real-world data sets.
