The SPET (Scanning Polarographic Electrode Technique) can measure dissolved oxygen gradients in aqueous media down to a fraction of a percent of concentration. An electrode is polarized to create a reduction reaction on the electrode tip. Different types of polarized electrodes can be utilized as well. Clark, Whalen and cathode type oxygen electrodes, carbon fiber based nitric oxide electrodes can be used along with many other types of polarized electrodes.
A complete SPET system contains:

  • IPA-2  Ion/Polarographic amplifier

  • RP-1 Research Platform

  • 2HDM-1  2 head stage mounting assembly with micromanipulator for simultaneous recording with two different electrodes.

  • FC-1 Faraday cage
