APPARATUS FOR CONDUCTING MEASUREMENTS OF ELECTROCHEMILUMINESCENT PHENOMENA |
摘要 |
An apparatus for conducting measurements of electrochemiluminescent (ECL) phenomena includes a cell unit having an electrode configuration for inducing the emission of ECL light by the application of a selected voltage waveform to a sample fluid including an ECL moiety. The sample fluid is transported to and from the cell unit by a flow-through pump/tubing system. A photomultiplier tube detects the intensity of light emitted by the sample fluid during the ECL measurement process. A computer control unit both analyzes the detected data and provides digital control signals to the cell unit to generate effective voltage waveforms. The digital control signals are supplied to a novel pulse width modulated digital to analog converter which outputs a ramp voltage waveform having the desired slope.
