Record the presence and concentration of oxidisable biological compounds in vivo and in vitro
Use with WPI's carbon fibre microelectrodes
The MicroC measures oxidisable compounds such as catecholamines (epinephrine, norepinephrine, dopamine), indolamines (serotonin, melatonin), ascorbic acid and Fe (II) with exquisite sensitivity, low noise and site specificity.
MicroC, WPI's low cost and elegant instrument for electrochemical detection using carbon microelectrodes, will record the presence and concentration of oxidisable biological compounds in vivo and in vitro. It also features inherently low noise and a sensitivity of 1 millivolt per picoampere of oxidation current. Response time to quantal catecholamine release is less than 1 millisecond. When used with carbon fibre microelectrodes, redox current can be recorded over a range of 1 picoampere to 2 microamperes. The built-in carbon electrode activation feature allows the easy renewal of electrode sensitivity. In addition, MicroC features a low-pass filter and the option of applying DC potential externally. Compounds such as glutamate, glucose, acetylcholine and alcohol, can also be detected with MicroC using enzyme-modified biosensors. The MicroC potentiostat is supplied with a carbon electrode probe, with 1.5m triax cable, which accepts 0.79mm connector pin, and a reference electrode with a 4mm Ag/AgCl half cell.
