ABSTRACT:
A method and apparatus is provided for measuring the content of a compound in a liquid medium, and which is particularly useful for measuring the concentration of a low molecular weight compound in a complex medium in which there is provided a dialyzer in contact with the complex fluid medium and through which dialysis fluid is conducted to receive by diffusion a portion of the low molecular weight compound to produce a dialysate. The dialysate with the low molecular weight commpound to be examined is first conducted through a venting device for removal of gaseous particles therefrom before conduction through a reaction chamber containing enzymes for promoting the conversion of the low molecular weight compound in the dialysate into a converted reaction product. The dialysate is then conducted from the reaction chamber to a measuring unit for measuring the concentration of the converted reaction product in the dialysate conducted from the reaction chamber, the concentration of the converted reaction product being representative of the content of the low molecular weight compound in the complex fluid medium.
