 Dioxins
and PCBs belong to the group of compounds known as Persistent Organic
Pollutants (POPs). They are known to bio accumulate due to their
lipophilic nature and, therefore, have health implications. As a
result, their emission into the environment and food chain is strictly
controlled. Samples that are analyzed, amongst others, are foodstuffs
like fish, fish feed, and stack emissions from waste incineration
sites.
The Supelco Dioxin Prep system provides a highly efficient means of extracting
and isolating dioxins, furans, and PCBs from stack gases, wastewater, soil,
food, blood, and milk. The Supelco prep system design offers:
- Reduced solvent usage
- Decrease in sample preparation time (by 2 days relative to conventional
methods) – see comparative overview chart
- Extraction recoveries greater than 85%

this application area, download a copy of the “Dioxin
& PCB Analysis” brochure. This contains information
on the two versions of the Dioxin Sample Prep System , GC columns,
sampler and resins for gas/air sampling, as well as suitable solvents.

The convenient multi-layer silica gel column is key to the extraction
process; seven layers of treated silica oxidize, reduce, and separate
polar interferences. The modular glassware and hardware design makes it
convenient for analysts to select a few system components or the entire
prep system for their extraction needs.

After removing interferences, the analytes are retained in-line either
on a Dual-Layer reversible Carbon column or on a Florisil micro-column.
After elution from the column, the analytes are typically analyzed by
gas chromatography (GC).
