1. An optical spectral sensing device, for determining properties of a sample, said device comprising:

  • an integrated energy source and an integrated spectral sensing detector package having a spectral sensing detector;

    an optimized sample chamber or cell dimensionally designed to match the active area of the spectral detection device without the aid of additional interfacing optics;

    integrated electronics for providing energy for said source and for receiving a signal generated by said spectral sensing detector in response to energy coupled to said detector by said sample chamber or cell, said integrated electronics providing direct output of sample properties of said sample;

    on-board computer processing with a microcomputer or digital signal processor, which includes memory storage for data, calibration coefficients, methods and results;

    on-board data communications including output to a visual display, communications of results to a process monitoring computer, and the option for wireless communications to an optimized network; and

    apparatus for disposable sample handling for ease of use, and to minimize sample contamination.
