1. A chromatograph analysis system for minute samples comprising in combination:

  • a separation column having an output end;

    a buffer solution reservoir;

    means for refrigerating said buffer solution reservoir to minimize the tendency for mold organisms to grow and produce particles which might plug the analysis system;

    inert gas means connected to said buffer solution reservoir for pressurizing buffer solution held therein;

    means for combining a sample and buffer solution from said reservoir and passing them through said separation column;

    heater means interposed between said buffer solution reservoir and said separation column to drive off inert gas dissolved in said buffer solution due to refrigeration thereof;

    a ninhydrin reagent reservoir;

    means for delivering ninhydrin reagent from said ninhydrin reservoir and combining said reagent with the buffered sample effluent from said column; and

    means for colorimetrically analyzing the combined flow of buffered sample effluent and ninhydrin reagent.
