Portable lead analyzer to locate source of lead

by Thermo Scientific Niton Analyzers  (Jan. 1, 2004)

OBJECTIVE: To investigate the sources of lead in the environment in children with elevated blood, with the help of a Field Portable X-Ray ...

Portable PMI Instruments

by Thermo Scientific Niton Analyzers  (Jan. 2, 2005)

Positive material identification (PMI) is a powerful methodology for assuring that manufacturing companies operate with greater profit, more efficiency, and the highest possible leveis of safety. The requirement for PMI of alloy materials in refinery systems and petrochemical plant operations has grown dramatically from the late 1970s when it was ...

Lead (Pb) on Surfaces by a Portable X-Ray Fluorescence (XRF) Analyzer

by Thermo Scientific Niton Analyzers  (Jan. 1, 2003)

This surface sampling method was developed to provide a reliable, portable procedure that will provide prompt measurement of surface contamination levels of lead. Information gained from samples taken during an initial walk-through portion ...

Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer

by Thermo Scientific Niton Analyzers  (Jan. 1, 2003)

Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton ...

Determination of the feasibility of using a portable x-ray fluorescence (XFR) analyzer in the field for measurement of lead content of sieved soil

by National Environmental Health Association (NEHA)  (Mar. 1, 2008)

Soil samples collected in housing areas with potential lead contamination generally are analyzed with flame atomic absorption spectrometry (FAAS) or other laboratory methods. Previous work indicates that field-portable X-ray fluorescence (XRF) analysis is capable of detecting soil lead levels comparable to those detected by FAAS in samples sieved ...

Handheld XRF analyzer, X-MET7000, for rapid, non-destructive Drywall testing – New application note from Oxford Instruments

by Oxford Instruments Industrial Analysis  (Jan. 30, 2012)

The handheld XRF analyzer - X-MET7000 - offers a rapid and non-destructive solution for screening of tainted and potentially hazardous Chinese drywall and for lead inspection. At the height of the U.S. housing boom, when building materials were in short supply, American construction companies used millions of pounds of imported drywall ...

Quantification of Ultra Low Sulfur in Diesel by Xray Fluorescence

by Eastern Applied Research, Inc.  (Jul. 21, 2011)

ASTM International has developed a number of testing methods for determination of sulfur content that focus on a variety of analyzer technologies but ASTM Method D4294 is the one that focuses on the use of energy dispersive x-ray fluorescence (EDXRF); which offers a relatively low cost analysis method that achieves fast results with ...

EPA Method 6200 and Field Portable X-ray Fluorescence Safety

by Thermo Scientific Niton Analyzers  (Jan. 1, 1998)

Overview: These training notes provide a brief introduction to x-ray fluorescence (XRF) analysis of soils. XRF has been used to characterize a broad range of materials for over twenty years. Recent advances in digital electronics and semi-conductor technology has yielded very portable XRF analyzers for field analysis of many sample types including ...

Hired metals analyser ensures remediation success

by Ashtead Technology Ltd  (Aug. 21, 2012)

Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been ...

Detecting Arsenic in Soil using Field Portable X-Ray Fluorescence

by Thermo Scientific Niton Analyzers  (May 1, 1997)

Abstract Rapid, accurate on site determination of arsenic and heavy metal levels in soil is a powerful tool in efforts to rebuild and revitalize abandoned and under-utilized industrial properties. The EPA is actively spearheading initiatives to encourage assessment, clean-up and re-use of these industrial properties. In the case of heavy metals ...
