  • Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables low limits of detection and easy automation of the whole method. ...

  • Analysis of Na, K, Ca and Mg in Mineralwater using the Microsampling Method

    Sodium, Potassium, Calcium, and Magnesium belong to the essential mineral substances in the human organism. These elements take influence in the generation of enzymes and hormones, control the osmotic pressure in tissues and body fluids and are important for the exchange procedures in the cell membranes. In this application, the control of Na, K, Ca and Mg in a variety of mineral waters has been ...

  • The Perfect Lab Partner For Compliance

    In July 2011, the NELAC (National Environmental Accreditation Conference) standards were revised as the new The NELAC Institute (TNI) Standard 2009, based on ISO 17025 guidance. Implementation of this updated TNI standard by the respective accrediting bodies will become a reality in the next year, though many have already implemented the new standard. For water system operators and testing labs, ...

  • Design of a Large Calibration Chamber

    The design and operation of a conceptually simple, low-cost chamber for calibration of cone penetrometers and other in situ devices is described. The chamber weighs over 5500 kg and houses a 4400-kg soil sample that is 1.5 m in diameter and height. Operations in the chamber are automated using a self-equilibrating hydraulic insertion frame, a soil pluviation system for sand placement, a vacuum ...
