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.

采用多种传感原理的多传感器阵列是研究领域的迅速发展分支，因其能够对复杂样本中的各种参数进行简单且经济的量化。此类系统的定量分析基于多元回归技术，而对于此类系统传统分析指标（例如，灵敏度、选择性、检测限和定量限）的推导并非显而易见且直截了当。尽管如此，这对于多传感器研究领域的进一步发展以及将此类仪器引入分析化学的普遍背景中至关重要。在此，我们报告了计算多传感器阵列灵敏度、选择性和检测限的协议。对于几个实际数据集，结果被详细提供并进行了讨论。
