Applications of a new instrument, the potentiophotometer.

The Potentiophotometer is a new instrument for measuring the absorption characteristics of solutions. A brief description of its construction and theory of operation is presented, with illustrations of its use in the colorimetric quantitative analysis for inorganic phosphorus and total protein in serum. The potentiophotometric results correlate well (r = 0.97 to 0.98) with measurements made of the same solutions with either of two conventional spectrophotometers, the Gilford 300N and the Coleman Jr. II.

Reuse of a disposable dialyser for home dialysis.

A disposable parallel flow plate dialyser (Gambro Lundia) has been evaluated. It is comparable in surface area and efficiency to the standard Kiil dialyser and can be regularly reused six times, combining the reliability and convenience of a prefabricated, factory-tested unit with the low cost of the Kiil dialyser.

Potentiophotometry.

The present derivation relates, in terms of analytical chemical photometry, the theory of operation of an extremely simple instrument which embodies both the electrical analog solution to Beer's Law of Spectrophotometry and the multiplication of this solution by a constant, such that the voltage reading of the instrument is identical to the concentration of the light absorbing substance being measured. Because the raw output of the instrument is both linear and proportionable, calibration of the instrument is accomplished by appropriately setting and positioning the potential difference between two known standard solutions. The determination of the concentration of an unknown solution is then the direct reading of the voltage it generates in the system. This approach to measurement is called Potentiophotometry, because it is based on potentials generated from light.
