Emergence of new and more dangerous environmental threats is a constant occurrence. Regulatory requirements change quickly and frequently with very little warning. Industries and organizations must have innovative and advanced analytical techniques that allow them to meet the challenges of this disruptive environment and yet continue to improve their methodology for art conservation, efficiently manage waste and reliably screen pesticides.
The EU Directives on Restriction of Hazardous Substances (RoHS) and End of Life Vehicle Directive (ELV) holds companies directly responsible for ensuring their products conform to strict standards, and the products sold in the EU do not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated biphenyl ethers (PBDEs) above the legal threshold. Manufacturers need to ensure that their products, parts, and components comply with the RoHS & ELV Directives in order to be distributed and sold in the EU.
Use of X-Ray Fluorescence (XRF) Analyzers for screening is a cost effective method to determine compliance levels in products and parts. XRF analysis can quickly and accurately identify the presence of these substances in their elemental form without any sample preparation.

The history of the land and past or present environmental threats in the area may indicate a high risk of finding heavy metals in the soil. Build sites that were once used for industrial purposes, or for orchards or farm land, are at a higher risk for the presence of heavy metals. Spills, runoff, or aerial deposition of chemicals used for agriculture or industry can also cause soil contamination in residential areas. The amounts of some soil elements may exceed EPA levels recommended for the health of humans, animals, or plants.
X-Ray Fluorescence (XRF) technology can be used to detect contamination in soil. Of the 13 EPA Priority Pollutant metals found in soil, 12 can be detected, specifically Antimony (Sb), Arsenic (As), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Mercury (Hg), Nickel (Ni), Selenium (Se,) Silver (Ag), Thallium (Tl) and Zinc (Zn).

Art & Conversation
Precious artifacts and historical monument are often affected by decay and through environmental pollution, vandalism, climate change, lack of budgets or just simple neglect. Conservators around the world are working day by day to save the world’s heritage for the future.
XRF technology is non-invasive and non-destructive and ideally suited for the study of art, museum, and cultural heritage objects. An XRF analyzer provides the elemental qualitative and quantitative information on functional groups and compounds in the material.
The globalized food supply chain poses serious challenges to producers, brands, consumers and governments. Increased worldwide competition, a growing number of contaminants and a strong demand for better food quality control are causing the governing Regulatory Agencies to enact more stringent regulations at an increasing frequency.
Food safety and security initiatives are indispensable for businesses that supply, market, or handle foodstuffs.
