  • Heavy Metal Compliance per RoHS Directive - Case Study

    Background Compliance with RoHS (or the Restriction of Hazardous Substances Directive) is an important issue in manufacturing today. RoHS has been constantly evolving since its original adoption in the EU as RoHS 2002/95/EC in 2003. Its full name is “Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment.” As the ...


  • Preparation and characterization of iron-copper binary oxide and its effective removal of antimony(III) from aqueous solution

    An Fe-Cu binary oxide was fabricated through a simple co-precipitation process, and was used to remove Sb(III) from aqueous solution. X-ray diffraction, scanning electron microscopy, energy dispersive X-ray and N2 adsorption–desorption measurements demonstrated that the Fe-Cu binary oxide consisted of poorly ordered ferrihydrite and CuO, and its specific surface area was higher than both iron ...

  • Analysis of Highly Mineralized Aqueous Solutions by ICP-AES

    Environmental Inductively Coupled Plasma (ICP) methods, such as EPA 200.7 or SW846 Method 6010, expect that samples will be fairly dilute without an overabundance of dissolved constituents (less than 2000 ppm Total Dissolved Solids). Laboratories running mine-impacted waters, such as acid rock drainage from exposed copper tailings, or mineral digests of a “waste” sample (that is ...

  • Case study - Sheet metal fabrication & surface wipe analysis

    A manufacturing company uses cutting oils to produce sheet metal to assemble elevators. The metal must be cleaned after production. Wipe samples were collected by the client and sent to Sitelab to monitor and adjust a new cleaning system ...

  • Matrix LIMS Brings Time Savings and Efficiency Gains - Case Study

    By replacing an inflexible LIMS with MATRIX Gemini LIMS, the analytical laboratory at a leading metal refiner has been able to incorporate 100% of its test records and results. The Autoscribe Informatics LIMS solution can be easily configured to meet the laboratory workflow rather than laboratory practices being adjusted to fit the LIMS. Ongoing in-house configuration has refined procedures to ...

  • Bioaccessibility tests accurately estimate bioavailability of lead to quail

    Hazards of soil‐borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb‐contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb ...

  • Adsorption studies of Cu(II) onto biopolymer chitosan and its nanocomposite 5%bentonite/chitosan

    Chitosan (CS) and nanocomposite 5%bentonite/chitosan (5%Bt/CS) prepared from the natural biopolymer CS were tested to remove Cu(II) ions using a batch adsorption experiment at various temperatures (25, 35 and 45°C). X-ray diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis/differential thermal analysis (TGA/DTA) were used in CS and the nanocomposite ...

  • Copper status of exposed microorganisms influences susceptibility to metallic nanoparticles

    Although interactions of metallic nanoparticles (NP) with various microorganisms have been previously explored, few studies have examined how metal sensitivity impacts NP toxicity. Herein, we investigated the effects of copper nanoparticles' (Cu‐NPs) exposure to the model alga, Chlamydomonas reinhardtii, in the presence and absence of the essential micronutrient copper. The toxic ranges for ...
