Environmental Analysis – An Electrochemical Contribution
28 May 2015In this white paper learn how electrochemistry plays a crucial role for all environment compartments, i.e., water, air and soil. In water, microbial fuel cells extract energy from wastewater, and Potentiostats monitor the associated electron transfer kinetics. In contaminated soils, Potentiostats track the redox reactions and the electrokinetic transport involved in electroremediation processes. Last but not least, Potentiostats track the electrochemical reactions that take place on catalyst surfaces – the place, where the greenhouse gas CO2 is reduced to produce reactive carbon monoxide or methanol.

Autolab PGSTAT101
Metrohm AGThis is the smallest member in the Autolab range of electrochemical instruments: the Autolab PGSTAT101. In combination with the powerful NOVA software it can be used for most of the standard electrochemical techniques. The PGSTAT101 is an affordable potentiostat/galvanostat without compromising on quality and specifications, making it an ideal instrument for students and educational purposes.The small footprint allows you to place a high quality potentiostat/ galvanostat on a crowded workbench. Analog and digital inputs and outputs for interfacing and controlling Autolab accessories and external devices are available.The Autolab PGSTAT101 comes with an internal dummy cell and is 9 x 21 x 15 cm3 for 2.1 kg.A transport case is available for the PGSTAT101.
Autolab PGSTAT302N
Metrohm AGThis modular high current potentiostat/ galvanostat, with a compliance voltage of 30 V and a bandwidth of over 1 MHz, combined with our FRA2 module, is specially designed for electrochemical impedance spectroscopy. The PGSTAT302N is the succesor of the popular PGSTAT30. The maximum current is 2 A, the current range can be extended to 20 A with the BOOSTER20A, the current resolution is 30 fA at a current range of 10 nA. With a special modification, the PGSTAT302N also offers the possibility to perform Dynamic iR compensation.
