Commercialization of LIBS for Lead-in-Paint Inspection
نویسندگان
چکیده
A study was undertaken to determine if laser-induced breakdown spectroscopy (LIBS) can be a practical and competitive alternative to X-ray fluorescence (XRF) methods for lead-in-paint inspection. Experiments in the laboratory confirmed that LIBS is suitable for detecting lead in paint at the hazard levels defined by federal agencies. Although we compared speed, function and cost, fundamental differences between the XRF and LIBS measurements limited our ability to make a quantitative performance comparison. While the LIBS method can achieve the required sensitivity and offers a way to obtain unique information during inspection, the current component costs will likely restrict interest in the method to niche applications. © 2008 Optical Society of America OCIS codes: (140.3440) laser-induced breakdown; (300.2140) Emission spectroscopy; (280.1545) Chemical analysis 1. Background A. On-site Lead-in-Paint Inspection Since 1977, the United States Environment Protection Agency (EPA) and department of Housing and Urban Development (HUD) have prohibited the manufacture and use of commercial paint

LEAD TOXICITY IN EMPLOYEES OF A PAINT FACTORY
Lead-based paint is an important cause of lead poisoning. This report describes our observation of excessive lead absorption among employees in a paint factory in which lead naphthenate and lead oxalate were used as drying agents in paint. In this study, blood levels of lead were compared between nineteen paint factory employees and twenty normal controls. The nineteen paint factory employ...
متن کاملA novel rapid quantitative analysis of drug migration on tablets using laser induced breakdown spectroscopy.
There have been few reports wherein drug migration from the interior to the surface of a tablet has been analyzed quantitatively until now. In this paper, we propose a novel, rapid, quantitative analysis of drug migration in tablets using laser induced breakdown spectroscopy (LIBS). To evaluate drug migration, model tablets containing nicardipine hydrochloride as active pharmaceutical ingredien...
