Systems, tools, and methods are presented for processing a plurality of spectral ranges from an electromagnetic radiation that has been interacted with a fluid. Each spectral range within the plurality corresponds to a property of the fluid or a constituent therein. In one instance, a series of spectral analyzers, each including an integrated computational element coupled to an optical transducer, forms a monolithic structure to receive interacted electromagnetic radiation from the fluid. Each spectral analyzer is configured to process one of the plurality of spectral ranges. The series is ordered so spectral ranges are processed progressively from shortest wavelengths to longest wavelengths as interacted electromagnetic radiation propagates therethrough. Other systems, tools, and methods are presented.
