Demanding electrochemical applications require high performance instrumentation coupled with high throughput capabilities
Trogone Instruments has launched its latest multichannel potentiostat, the VMP3.
Princeton Applied Research recognises that researchers in battery evaluation and development or electrochemical sensors have equipment demands that are sometimes hard to satisfy with conventional potentiostats and galvanostats.
To address these applications Princeton Applied Research has introduced the VMP3 series of multichannel instruments.
The next generation of multichannel instruments comes with improved specifications or features not available on the VMP2.
However existing users have not been forgotten as the original VMP2 base unit is capable of supporting the new VMP3 and VMP3/Z channels.
The VMP3 has a maximum continuous current specification of 400mA on each channel.
Each channel can be boosted up to 80amps.
Programmable compliance voltage is a new VMP3 feature.
The VMP3 has a 20V compliance specification.
Because the VMP3 is a virtual ground instrument, the compliance voltage can be adjusted based on where the virtual ground is set.
The VMP3 has two general-purpose analogue inputs with programmable ranges.
These can be used to record temperature, pressure, or another variable that can be converted to a voltage.
There is also a TTL signal in and TTL signal out to enable experiments to coordinate precisely with other instrumentation events that could be necessary in an experiment.
The VMP3 units can be outfitted with the EIS option.
This option allows for a built-in impedance analyser capable of performing electrochemical impedance spectroscopy from 10uHz to 400kHz.
A VMP3 unit outfitted with multiple EIS capable channels can perform simultaneous impedance experiments on each channel.
A VMP3 unit can contain a mixture of EIS channels and non-EIS channels.
The firmware for the VMP3 can be downloaded from the newest version of the software available.
In this way, as new techniques are implemented in the software, the proper firmware modifications can be downloaded to the VMP3 hardware unit to allow the unit to execute the necessary commands.
The VMP3 Windows-based software (95, 98, ME, NT, 2000 and XP) performs a variety of electrochemical techniques from basic electrochemistry to corrosion/impedance to battery test.
Each of the techniques provides flexible user input, technique specific plotting formats, and data analysis tools.
