Abstract
Optical computing devices are disclosed. One exemplary optical computing device includes an electromagnetic radiation source configured to optically interact with a sample and first and second integrated computational elements arranged in primary and reference channels, respectively, the first and second computational elements are configured to be either positively or negatively correlated to the characteristic of the sample. The first and second integrated computational elements produce first and second modified electromagnetic radiations, and a detector is arranged to receive the first and second modified electromagnetic radiations and generate an output signal corresponding to the characteristic of the sample.
