Abstract
A new portable capillary electrophoresis instrument with capacitively coupled contactless conductivity detection was
developed and optimized for the sensitive field measurements of ionic compounds in environmental samples. 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.
