  • 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: ...


  • Determination of arsenic in baby foods and fruit juices by GFAAS

    The United States does not have specific regulations specifying the allowable levels of toxic elements in foods, but many other countries do. For example, Canada has a specific tolerance level for arsenic of 0.1 ppm in ready to serve fruit juices, nectars, and beverages1.
