Stromkreis zur Erzeugung einer Elektrolysenspannung für Polarographe

Chemical analyzer - for dissolved substances using electrical detection and comparison of titrated test and refere

The test soln. (which can be of medicinal-clinical, biochemical or industrial nature) is dispensed into a reaction chamber together with a reagent and measured amount of reacted mixture fed into a dilution chamber where it is continuously diluted with a solvent whilst a suitable physical characteristic is measured and converted into an electrical signal which is compared, also continuously with the electrical reference equivalent to that produced by a standard soln., i.E, one with known conc. of the substance being determined. When the balance condition is reached the feed of solvent is stopped and from the electrical reading at that point the conc. in the test soln. is computed. Fully automatic system which can be incorporated in a larger installation.
