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 ...

Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.

by Thermo Scientific Niton Analyzers  (Aug. 4, 2010)

X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, ...

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 ...

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 ...

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 ...

Analyzing sulfur in soil and sediment with handheld XRF

by Thermo Scientific Niton Analyzers  (Aug. 4, 2010)

Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material ...

Get the Lead Out - Standards Aid in RoHS Compliance

by ASTM International  (Nov. 6, 2014)

RoHS, the seminal European sustainability directive, and others like it challenge manufacturers to eliminate hazardous substances in their products. With RoHS compliance deadlines ongoing through at least the next five years, and more to come from other regions and nations, ASTM Committee F40 is helping companies with testing standards and other ...

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 ...

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 ...
