NPL offers a very accurate and rapid service for measurement of the total particulate-phase mass of a range of metals on filter material or mass fraction in acid solutions, as required for characterising emissions from waste incinerators and similar facilities. We have ISO 17025 accreditation for the following metals: arsenic, cadmium, mercury, nickel, lead, platinum, chromium, copper, cobalt, iron, thallium, manganese, vanadium, antimony and zinc.

Samples, in the form of filters and liquid washings, are analysed for their metals content by inductively coupled plasma – mass spectrometry (ICP-MS), a technique employing an argon plasma to ionise a sample. The gaseous ions produced are then analysed by a quadrupole mass spectrometer.

The procedure is compliant with EN 14385 and EN 13211 and has a typical detection limit of 5 ng of metal per filter.

NPL also has MCERTS accredited emissions monitoring teams - click here for further details.
