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 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.
