  • Air crash investigation using Oxford Instruments handheld analysers - case study

    It was late April 1945 during the last days of World War II for Italy. Just one week before the liberation of Italy from the fascists rule, a group of five Messerschmitt BF 109 planes took off from the Vicenza airbase heading to Ghedi, near Brescia. This was not a combat mission but a transfer flight. Soon after take-off the planes were intercepted by US fighters and attacked. All five planes ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • The determination of major and minor elements in air filters and urine for hazard assessment, using a new CCD DUAL-VIEWED ICP optical emission spectrometer

    This article describes the application of a new type of CCD-based, dualviewed ICP optical emission spectrometer for the analyses of industrial hygiene types of samples. Several trace elements in air filter media are determined by ICP-OES. Urinary electrolytes and trace elements are determined in a single dilution automatically in both the axial and radial plasma viewing orientations. Results of ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...
