Computer-controlled two-channel potentiostat/galvanostat can perform electrochemical impedance spectroscopy
Trogone Instruments announces the release of another new product to the family of multi-channel potentiostats.
The Par Bi-Stat/Z is a second version of the popular Bi-Stat unit, with one of the channels having the low current option board and being EIS (electrochemical impedance spectroscopy) capable.
The Bi-Stat/Z is a computer-controlled two-channel potentiostat/galvanostat. Each channel of the Bi-Stat can be controlled independently or used in conjunction with each other to perform the same or a different experiment on different electrodes.
In addition, the two channels can be used with one common reference and one common counter electrode (Bi-Stat mode).
It is, says Trogone, the only bi-potentiostat on the market that can be used as two separate full-function potentiostats.
One of the channels of the Bi-Stat/Z can perform EIS measurements with a frequency range from 10uHz to 200kHz and is equipped with the low current option providing sub-pA resolution.
Either channel can be interfaced to a current booster for high current applications.
Provision is made for control of an electrode rotator such as the Par model 616 or 636 and auxiliary A/D converters allow for the input of external signals from ancillary equipment such as pH and temperature probes or a quartz crystal microbalance.
Princeton Applied Research offers over 25 electrochemical techniques for the Bi-Stat.
These techniques include cyclic voltammetry, differential pulse and chronoamperometry for basic electrochemical research.
For corrosion, there are the standard corrosion techniques, plus multielectrode techniques that utilise the N-stat feature of the bi-potentiostat, where two working electrodes can be used with one reference and one counter electrode.
The Bi-Stat is said to be ideal for hydrogen permeation studies.
In the battery application area, there are dedicated protocols to perform accepted test procedures on fuel cells and batteries.
