  • Relating Certain Concepts

    I wrote about a forty year logarithmic growth of technology in the April 2007 issue of Lab Manager . We talked about increasing numbers and kinds of instruments, the increasing number of analytes, the need for greater and greater sensitivity, and the need for data validation and normalization. Let’s now tackle that first facet – instrumentation. Instruments are developed for a few basic reasons: ...


  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...
