3. The Instrument
3.1 The
principle
The differential pH technique is based on the correlation of pH variations, which are
measured by two capillary glass electrodes, to the quantity of H
+
produced or consumed by
a reaction, which is started by adding the necessary enzyme or substrate.
3.2
The Measuring System.
The CL10 Plus is a compact and easy to operate instrument. It is made of a differential
amplifier and a microprocessor which calculates the analyte concentration or enzyme
activity in the sample, and controls all the functions of the instrument.
The mechanical components are:
