Scope: This standard specifies the inductively coupled plasma mass spectrometry method for the determination of 65 elements in water. This standard applies to silver, aluminum, arsenic, gold, boron, barium, beryllium, bismuth, calcium, cadmium, cerium, cobalt, chromium, cesium, copper, dysprosium, erbium, Europium, iron, gallium, gadolinium, germanium, hafnium, holmium, indium, iridium, potassium, lanthanum, lithium, lutetium, magnesium, manganese, molybdenum, sodium, niobium, neodymium, nickel, phosphorus, lead, palladium, praseodymium, platinum, Determination of rubidium, rhenium, rhodium, ruthenium, antimony, scandium, selenium, samarium, tin, strontium, terbium, tellurium, thorium, titanium, thallium, thulium, uranium, vanadium, tungsten, yttrium, ytterbium, zinc, zirconium. The detection limit of each element in this method is 0.02~19.6 μg/L, and the lower limit of determination is 0.08~78.4 μg/L. Please see Appendix A for the method detection limits of each element.
