  • Using FIMS to determine mercury content in sewage sludge, sediment and soil samples

    Tim Flow Injection Mercury System (FIMS) is a dedicated system that integrates flow injection mercury cold vapor generation with a very sensitive detector. The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the ...

  • Analysis of low levels of metals in drinking water with a scanning array ICP emission spectrometer and ultrasonic nebulization

    Drinking water is an important factor in exposure to environmental contaminants and is used in preparing foods and beverages for human consumption. Therefore, great care is used to verify that it is free of or contains acceptable limits of toxic substances. With respect to heavy metals and other toxicologically relevant elements, atomic spectrometric techniques are frequently used to determine ...

  • Life Among The Heavy Metals

    Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

  • The Gasmet story from an academic idea to a global business

    In this article, Dr Petri Jaakkola, founder and Chairman of Gasmet Technologies Oy explains how an idea shared by a group of researchers at the University of Oulu in Finland, during the early 1970s, developed into one of the world’s leading gas monitoring instrumentation manufacturers. Early history – technology development At first, the Finnish researchers understood ...

  • The African crested rat’s poisonous hairs studied by attenuated total reflection infrared spectroscopy case study

    Introduction Plant toxins are commonly used by many invertebrates, as an effective defence against predation. However, such behaviour has recently been observed in a mammal.1 The African crested rat, Lophiomys imhausi, applies a potent toxin to the fur alongside its flanks. It acquires this toxin from Acokanthera schimperi,1 a shrub abundant in East Africa and dubbed the “poison arrow ...
