Incorporation Of Integrated Computational Elements Within Optical Analysis Tools Having A Miniaturized Operational Profile

An optical analysis tool comprising:

• an electromagnetic radiation source that provides electromagnetic radiation to an optical train, the electromagnetic radiation source comprising a planar, thermal blackbody emitter;
• an optical computing device positioned within the optical train, the optical computing device comprising a 2×2 planar array detector having at least two optical detection regions, at least one of the at least two optical detection regions having an integrated computational element disposed thereon;
• wherein the 2×2 planar array detector and the integrated computational element are in a fixed configuration with respect to one another;
• and
• tiered sampling windows within the optical train that define a portion of a flow pathway for a sample, the tiered sampling windows being sealed from the flow pathway and comprising a substance that is substantially transparent to electromagnetic radiation within the optical train.
