TestAmerica Announces Webinar on Analytical Methods for the Determination of 1,4-Dioxane

Knoxville, TN – WEBWIRE

TestAmerica, the leader in environmental testing, is pleased to announce the next installment in its Ask the Expert webinar series.  On Tuesday, May 23 at 1:30 P.M. EST, TestAmerica expert Eric Redman will present a webinar entitled A Comparative Review of Analytical Methods for the Determination of 1,4-Dioxane:  Which One Is Best For My Project? 
1,4-Dioxane has come under increasing regulatory scrutiny as concerns regarding its toxicity and potential impact on drinking water supplies has increased.  The requirement for accuracy at low detection limits creates significant challenges for both the analytical laboratory and data users.  High water solubility makes 1,4-Dioxane difficult to determine by historical analytical techniques such as EPA Methods 8260 and 8270.  Consequently, analytical laboratories have modified these conventional methods with a wide range of enhancements to improve the reliability and sensitivity of the base method.  Modifications include use of solid phase extraction, selected ion monitoring mass spectrometry, isotope dilution quantitation, large volume injection, micro-extraction, and a variety of other techniques.  Due to the lack of prescribed methodologies, TestAmerica offers a variety of techniques to meet the various state requirements.
Method variations lead to a wide array of analytical options with a range of performance characteristics.  This presentation will simplify the analytical permutations and focus on the most desirable modifications for specific data quality objectives.  Data users and project managers will understand the pros and cons of major method enhancements and how they are combined to provide the most cost-effective method for project-specific data quality objectives.
Eric Redman, Corporate Director of Technical Services at TestAmerica, has over 30 years of experience in the environmental testing industry, specializing in the application of analytical chemistry to environmental problems.
