ISO 17294-1

Water quality - Application of inductively coupled plasma mass spectrometry (ICP-MS) - Part 1: General guideline

Scope

This standard specifies a method for the determination of the dissolved elements silver, aluminium, arsenic, gold, boron, barium, beryllium, bismuth, calcium, cadmium, cerium, cobalt, chromium, caesium, copper, dysprosium, erbium, europium, gallium, gadolinium, germanium, hafnium, holmium, indium, iridium, potassium, lanthanum, lithium, lutetium, magnesium, manganese, molybdenum, sodium, neodymium, nickel, lead, palladium, praseodymium, platinum, rubidium, rhenium, rhodium, ruthenium, antimony, scandium, selenium, samarium, tin, strontium, terbium, tellurium, thorium, thallium, thulium, uranium, vanadium, tungsten, yttrium, ytterbium, zinc, and zirconium in aqueous solution (e.g. drinking water, surface water, waste water and eluates.
Taking into account possible interferences, these elements can also be determined in digests from sludges and sediments.
The lower limit of application depends on the matrix and the interferences encountered. In drinking water and relatively unpolluted waters, the limit of application is between 0,1 µg/l and 1,0 µg/l for most elements. The lower limit of application will be higher in cases where
the determination is likely to be interfered or in case of memory effects. For more detailed information, see the draft standard.
