Metals
Over thirty metal analyses are available for testing including Arsenic (As), Aluminium (Al), Boron (B), Barium (Ba), Cobalt (Co), Copper (Cu), Cadmium (Cd), Lead (Pb), Chromium (Cr), Iron (Fe), Maganese (Mn), Mercury (Hg), Nickel (Ni), Selenium (Se) and Zinc (Zn). A plasma -mass spectrometer is used for the analyses of these and other metals, supplemented by the use of plasma emission spectrometers and automated atomic absorption spectrometers. The determination of metals in water is important for a number of reasons: for example the metals may be toxic to the environment or they may cause bad tastes or excessive colour.
Major Cations
Calcium (Ca), Magnesium (Mg), Sodium (Na) and Potassium (K) make up the major cations present typically in waters. The concentrations of these cations signifcantly effect the quality of waters and can influence characteristics such as taste, hardness and corrosive tendency.
