These certified reference materials are useful to laboratories performing testing of environmental samples including paint, soil and dust for lead by atomic and emission spectroscopy
Environmental Reference Materials announces the availability of four new National Institute of Standards and Technology (Nist) traceable lead paint standards produced by Research Triangle Institute (RTI International).
They can be used in meeting quality control requirements of the American Industrial Hygiene Association's (AIHA) Environmental Lead Laboratory Accreditation Program (Ellap) that accredits testing laboratories under the US EPA's National Lead Laboratory Accreditation Program and as practice samples for laboratories participating in the AIHA's Environmental Lead Proficiency Analytical Testing program (Elpat).
The laboratories accredited under these programs are authorised under US regulations to perform testing to assess the hazard from lead-based paint in buildings, ships and surrounding areas undergoing abatement procedures.
LCS-401, Blended Paints from Public Buildings, contains 4430ppm lead. LCS-402, Lead Paint, contains 600ppm lead.
LCS-301, Northeast Urban Soil, contains 547ppm lead.
LCS-302, Blended Northeast Urban Soil, contains 5369ppm lead.
These certified reference materials are ideal as spiking materials or as separate quality control standards for use during testing of paints and soils for lead.
They have been tested against Nist Standard Reference Materials SRM 1579 (Lead Paint) and SRM 2704 (Buffalo River Sediment).
Results are also available for 11 additional elements including Cd and Cr.
They are packaged in 50g quantities and are on sale through 30 September 2004 through a buy one, get one free promotion at an introductory price of US$190 per unit.
Also available are ERM series Nist traceable lead free paint (<4ppm), lead free soil (<4ppm), lead paint (367ppm-35g units) and lead paint in soil (484ppm) and two non-Nist traceable lead paint in soil standards (558, 3395ppm).
The Nist traceable products are available in 50g units for $160/unit and the non-Nist traceable ones are available in 50g units for $60/unit.
