1. An apparatus for automatically collecting samples from a fluid stream and for monitoring at least one analyte on a real-time basis, according to at least one mode of operation selected by a user, comprising:

  • means for controlling said apparatus;

    a fluid sampling assembly having an inlet for receiving fluid from a fluid stream;

    power means for supplying power to said apparatus;

    said fluid sampling assembly, said control means and said power means comprising an integral operating unit;

    a fiber optic sensor for detecting values of said analyte in said fluid stream and for outputting signals related thereto, said fiber optic sensor being selectively connected to said integral operating unit; and

    said control means comprising a microprocessor, program memory and data memory, wherein;

    said program memory stores at least one equation for computing values of said analyte;

    said microprocessor receives said signals related to said analyte from said fiber optic sensor and utilizes said program memory to calculate values of said analyte based on said signals;

    said at least one mode of operation which may be selected by the user includes a first mode of operation in which sampling is triggered by at least one predetermined value of said analyte being monitored;

    said data memory stores user-selected input parameters including operating mode selection data and said at least one predetermined value of said analyte;

    said microprocessor controls said fluid sampling assembly according to said at least one mode of operation selected by the user, based on a deviation of computed values of said analyte from said user-selected predetermined value of said analyte; and

    said data memory stores fluid sampling data and analyte data.
