Automated Solid Phase Extraction for the Environmental Testing Laboratory

This presentation was recorded on September 24, 2014.


Today’s analytical laboratory is faced with tight deadlines to produce results from testing environmental samples. Too often, solid-phase extraction (SPE) presents a bottleneck in the analytical testing process and may cause poor analyte recoveries and highly variable. Despite advances in analytical instrumentation, sample prep often relies on tedious, manual, and expensive techniques such as liquid-liquid extraction.

Sample preparation of environmental water samples can be automated, however.. Use of automated sample preparation addresses the many challenges that laboratories face when preparing samples and can help improve sample processing turnaround times. The first part of the webinar will discuss how automated sample preparation can benefit analytical laboratories.

The second part of the webinar will present data from Orange County Water District (OCWD) where eight nitrosamines, 1, 4-dioxane and other emerging contaminants are monitored at sub parts per trillion levels. We will discuss the use of sample flow rate, elution time, drying time, and nitrogen gas flow rate as key operational parameters within the solid-phase extraction process to optimize the analytical step.
