Challenges in Extracting Perfluorinated Compounds in Drinking and Wastewaters
Perfluorinated compounds (PFCs) are a group of compounds that are highly resistant to degradation which allows them to accumulate in water sources, particularly those used for consumption. One of the biggest challenges when extracting these compounds is minimizing interferences and opportunities for contamination during sample preparation and analysis.
This webcast reviews EPA Method 537 on how to demonstrate lack of system contamination and sample-to-sample carryover. Data is presented for the extraction of up to 24 PFC compounds on an automated solid phase extraction system in multiple water matrices, following the requirements in EPA Method 537.
Updated MUR allows SPE in US EPA Method 625.1
What does this mean to you? Updated methods for a variety of analytes in wastewater are now available, including 608.3 (organochlorine pesticides), 624.1 (volatiles), and 625.1 (semivolatile). Disk solid phase extraction has been used with method 608 for more than 20 years, now you can use it for method 625.1, expanding the methods you run using SPE to all major EPA programs.
This webcast discusses the use of solid phase extraction (SPE) in environmental methodology. The impact of the Method Update Rule (MUR) is discussed along with the requirements for use of SPE in the wastewater program outlined. The full data package generated by Horizon Technology to ensure compliance with the new validation requirements is discussed and the data summarized.

Evaporation Made Easy - Improved Evaporation and Concentration for Better Chromatographic Analysis
Sample preparation is a key part of the analytical process, contributing to reproducibility and accuracy in the final results. The evaporation/concentration step can be achieved with various technologies, including heat, vacuum, and blow-down. We will examine the parameters that go into each of these choices and describe criteria to consider in matching the sample to the technique. Presented by Marc Hamel and John Siira, Horizon Technology.
Mycotoxins, Fluoroquinolones, Colors: Boosting Sample Preparation
Food safety is an increasingly important topic for our global food supply. Quality data are critical to ensuring safe food. Although many advances in the sensitivity and applications of analytical techniques have occurred, often sample prep has lagged behind. Solid-Phase extraction (SPE) has shown utility in both clean-up and concentration of food extracts. How do you move into automation of cartridge SPE? Improved accuracy and precision with less hands-on time for a variety of food safety analyses will show the utility of this approach.
Solvent Emission Reduction in the Modern Environmental Laboratory
Recent changes have caused laboratories to take a look at air emissions, mostly arising from solvent evaporation of organic extracts. Through Title V and State Implementation Plans up to 10 tons of chlorinated solvent and up to 25 tons total of solvent may be emitted with a valid permit. For extremely small emitters, no permit is required if they are not at risk of exceeding the limit. Presented by Bill Jones.
Recent advances in Solid Phase Extraction for the Determination of a Full Range of Organic Compounds from Challenging Samples
Solid Phase Extraction (SPE) is a well known and useful technique for the extraction of organic compounds from aqueous samples. This paper will address both the chemical and physical issues, and present data which shows that with proper use, that SPE can successfully be used to process typical environmental samples, effectively, efficiently, and provide comparable or better data than achieved now with conventional liquid/liquid extraction techniques. Presented by David Gallagher, Horizon Technology.
