  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Heavy Metals Analysis

    Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...


  • The Internet of Water Is Saving Lives While Battling Pollution

    The Problem A condition known as Legionnaires' disease has made headlines after it killed a dozen people in Flint, Michigan in 2014 and 2015 and sickened hundreds in  ...

  • Analysis of wastewater for metals using ICP-OES

    The analysis of wastewater for trace metal contamination is an important step in ensuring human and environmental health. Wastewater is regulated differently in different countries, but the goal is to minimize the pollution introduced into natural waterways. In the U.S., the Environmental Protection Agency (EPA), in conjunction with the states, negotiates a discharge permit through the National ...

  • X-ray fluorescence analysis of additives and wear metals in used lubricating oils

    The determination of metal concentrations in lubricating oils is a very important diagnostic development. Such analysis dates back over 50 years, when one of its earliest uses was to assess engine oil from trains. Today, the analysis of both new and used lubricating oils, as well as the monitoring of trends in the metal concentrations and additives they contain, has become an essential control. ...

  • Equilibrium analysis for heavy metal cation removal using cement kiln dust

    Ion exchange, reverse osmosis, and chemical precipitation have been investigated extensively for heavy metal uptake. However, they are deemed too expensive to meet stringent effluent characteristics. In this study, cement kiln dust (CKD) was examined for the removal of target heavy metals. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption ...

  • Retention of heavy metals by stormwater filtration systems: breakthrough analysis

    Biofiltration systems are widely used to mitigate the impacts of stormwater on receiving waters, however their long-term capacity to retain heavy metals has not previously been assessed. Accelerated-dosing laboratory experiments were used to assess the likelihood of breakthrough occurring for three different types of soil-based filter media that are commonly used in stormwater biofilters. In all ...

  • Oil and metal price movements and BRIC macro–economy: an empirical analysis

    Brazil, Russia, India, and China are the four fastest growing economies to emerge at the dawn of the new century. Concisely referred to as BRIC, the growth of these states has transferred sources of wealth and capital. To fuel such rising economies requires resources. In particular, food, construction materials, and energy are necessary to sustain BRIC growth. This paper will ultimately examine ...

  • Evaluation of Sampling and Field-Filtration Methods for the Analysis of Trace Metals in Ground Water

    Selected ground water sampling and field-filtration methods were evaluated to determine their effects on field parameters and trace metal concentrations in samples collected under several types of field conditions. The study focused on conditions where traditional approaches may produce turbid samples, which often leads to filtration of suspended particles from the sample before laboratory ...

  • Analysis of trace metals in drinking water with the optima 7000 DV ICP-OES

    With the development of mining, smelting and other industrial activities, heavy metals are increasingly being found in freshwater sources which can pose severe threats to human and environmental health. Pollution by heavy metals (such as Cd, Pb, etc.) not only affects the productivity of crops, but also the quality of the atmosphere as well as water bodies and threatens the health and life of ...

  • Are nanosized or dissolved metals more toxic in the environment? A meta‐analysis

    Recently, much has been written about the utmost urgency of elaborating the regulations for engineered nanomaterials. It is required from both politicians, to protect people from potentially adverse effects of nanomaterials, and from industry representatives, so that they can prove to have carefully and cautiously produced their nanoproducts and avoid potential court proceedings. However, ...

  • 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 ...

  • Mining Metals Solution Treatability

    Integrated Engineers, Inc. conducted a treatability test on water containing metals in solution from a mining company’s analysis labs. Initial pH was below 2, so it was adjusted to 6.5 to 7.5 using caustic. This lowers the solubility of the metals, and helps the Floccin to work better. The Floccin-1105 worked well at a dosage of 2.1 grams/ 1,000 ml of wastewater (treatment dosage of .9 lbs. of ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Ground Water Sampling for Metal Analyses

    The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA’s Regional Superfund Offices, organized to exchange up-to-date information related to ground-water remediation at Superfund sites. Filtration of ground-water samples for metals analysis is an issue identified by the Forum as a concern of Superfund decisionmakers. Inconsistency in EPA Superfund ...

  • Designing a relational database for tracking and analysis of atmospheric deposition of mercury and trace metals in the Pensacola (Florida) Bay Watershed

    The need to track and analyse the atmospheric deposition of mercury and trace metals in the Pensacola (Florida) Bay Watershed in recent years has resulted in the need for a data management system that will allow data to be efficiently stored, checked for errors, manipulated, retrieved for analysis and shared within the research community. In this paper, we describe a relational database that was ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
