The analysis of samples contaminated by organic compounds are an important aspect of environmental and food monitoring. The use of accelerated solvent extraction is well established technique in the environmental, chemical and food analysis markets. The benefit of accelerated solvent extraction is fast extraction of analytes compared to conventional extraction techniques, such as Soxhlet extraction.

The presence of moisture in the samples can occasionally interfere with extraction and analysis. In samples containing water, an additional pre or post extraction step is usually required. Sample drying can be accomplished by air drying or oven drying prior to extraction. However, these approaches are not only time consuming but also not suitable when analyzing volatile or semivolatile compounds. This web seminar explains the use of a proprietary new polymer designed to remove moisture and increase extraction efficiencies from wet samples including soils, tissues, and food products. The polymeric material can be used for both in-line and off-line drying applications. This highly automated and easy-to-use, robust method allows for the analysis of the most challenging sample types.

Key Learning Objectives:
  • Learn about the use of a proprietary new polymer designed to remove moisture and increase extraction efficiencies from wet samples including soils, tissues, and food products
  • Learn about the process of in-line drying using accelerated solvent extraction of wet samples
  • Learn about moisture removal from wet samples and extracts

Who Should attend:
  • Environmental and food chemists analyzing persistent organic pollutants (POPs), semivolatile organic compounds, and pesticides in wet matrices
  • Those interested in automation of extractions to increase sample throughput
