AN815: Automated Solid-Phase Extraction (SPE) of Waste waters and Surface Waters Using the Thermo Scientific Dionex AutoTrace 280 SPE Instrument for EPA Method 608

Instrument Type: Automated Sample Prep

EPA Method 608 uses liquid-liquid extraction by separatory funnel combined with gas chromatography and electron capture detector for the analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in municipal and industrial waste water. Unlike the drinking water methods, however, analysis of waste waters and the streams they flow into, need to contend with particulates. The Thermo Scientific™ Dionex™ AutoTrace™ 280 instrument has features that allow analysis of samples even with high amounts of suspended solids and is suitable for use in EPA Method 608.

A Strategy for an Unknown Screening Approach on Environmental Samples Using HRAM Mass Spectrometry

Instrument Type: LCMS

The analysis of food and environmental samples for contaminants by LC-MS has become a quick and cost-effective routine application when run in a targeted fashion, but this method disregards events or circumstances not taken into account beforehand. We describe a method by one data set can serve for routine high throughput quantitative analysis and for versatile non-targeted investigations in a highly automated manner.

Targeted and Nontargeted MS Analysis of Contaminants in Storm Water Retention Ponds

Instrument Type: LCMSMS

Comprehensive assessment of the aquatic fate and effects of organic micropollutants is greatly hindered by the need to develop compound-specific methodologies prior to sampling and analysis. We descrbe a data-driven workflow, coupling high-resolution, accurate-mass (HRAM) mass spectrometry and highly sensitive online solid phase extraction (SPE) analysis that ensures complete characterization of organic pollutants in aquatic environments.
