Apparatus for measuring electrolytes including optical measurements |
摘要 |
Apparatus for measuring electrolyte concentrations in fluid samples. The apparatus includes an ion selective electrode capable of generating a voltage differential having a magnitude related to the concentration of the corresponding electrolyte in the sample. A voltage to optical transducer circuit is provided to convert the voltage differentials to a digital code and then to an optical signal which is related to the concentration of the electrolytes. The optical signals are suitable for detection by conventional optical detector apparatus of assay instruments. A passive duplex transfer is utilized to simultaneously read one optical signal while transferring the next bit of the digital code. The duplex transfer configuration also makes novel use of the photodetection properties of an LED.
