    Wednesday, September 01, 2010
    Application Note
    Shaun Quinn
    Integration is a fundamental task that all chromatographers perform on a daily basis. Due to faster chromatography, which is creating more data every day, the amount of time spent on integration is ... read more

  • Efficient Use of Spectral Information Through Multiline Analysis in ICP-AES

    Wednesday, August 01, 2007
    Application Note
    Jean-Michel Mermet Agnès Cosnier Sophie Lebouil Sébastien Vélasquez
    The classical way to conduct the determination of an element in inductively coupled plasma-atomic emission spectrometry (ICP-AES) is to select a single line with adequate sensitivity and that is free... read more

  • Acidic Digestion of Soils to Determine Mercury Concentration

    Friday, June 01, 2007
    Technical Article
    Pamela F. Heckel Tim C. Keener
    Soils are notoriously heterogeneous and difficult to analyze. The authors developed a digestion method to extract mercury from clay soils using relatively inexpensive cold vapor atomic absorption ... read more
