A screening method for the essential oils in hops using solid-phase microextraction

Creator:

Heider, Chris

Abstract:

Separation and isolation of organic analytes from environmental matrices such as soils, water, plant, or animal tissue has traditionally involved the use of liquid solvent extractions. Solvent-based extraction methods are often time-consuming, difficult to automate, and use expensive solvents that generate hazardous waste and working conditions. The need for a...

Quantitative determination of DCPA and its metabolites using strong anion exchange solid-phase extraction with gas chromatography/electron capture detection

Creator:

Monohan, Keith

Abstract:

Rapid and accurate analytical methods are needed to assess the impacts of agricultural chemicals on soil and water resources. Solid-phase extraction (SPE) was evaluated as an alternative method to conventional liquid-liquid extraction for the quantitative analysis of the herbicide DCPA and its metabolites in ground waters. Strong anion exchange (SAX)...
