It is powered by batteries and the high voltage modules are capable of delivering up to 15 kV at either polarity for more than one working day. Inorganic cations and anions, including ions of heavy metals and arsenate, could be determined with detection limits in the range from about 0.2 to 1 mM. The instrument was field tested in a remote region of Tasmania and nitrite and ammonium could be determined on-site at concentrations as low as 10 ppb in presence of other common inorganic ions at concentrations which were 2 to 3 orders of magnitude higher. 2007 Electroanalysis 19 19-20 Wiley-VCH 2059-2065 10.1002/elan.200703908 TRUE 1040-0397 http://dx.doi.org/10.1002/elan.200703908 6836 3 3759 1 application/pdf en staffonly
