Dioxins and PCBsbelong to the group of compounds known asPersistentOrganic Pollutants (POPs).They are known to bio accumulate due to their lipophilic
(ll/!fllf!!refore,
have
health implications.
As
a result their emission into the environment and food chain isstrictly controlled. Samplesthat are analysed, amongst others, are foodstuffs like fish,fish feed,and stack
emissions from waste incineration sites.Limits are published by the World Health Organisation (WHO) and local authorities.
As
a consequence, low levelsof contamination have to be
detected, providing a challengeto samplepreparation and detection systems.
The term 'Dioxin' covers a wide range of halogenated aromatic compounds, including polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs and PCDFs).These
compounds are formed as a result of incomplete combustion of hydrocarbons in the presence of chlorine e.g.metal processing,domestic waste incineration, etc.They have high melting
points and are stable to acids and bases; these characteristics make them very persistent in the environment. PCDD/Fs can be found in many environmental matrices such as soils,
sediments,air;andwater.
In this work we present the use of our new GC-MS column, the MEGA-S MSXii, with aO.ISmm ID, 30m configuration, that will provide enhanced separation of almost all highly toxic
2,3,7,8-PCDD/Fs from other isomers,while also significantlyspeeding up the GC-HRMS analysis of Dioxins and Furans, with exceptional peak shapethank to our unsurpassed inertness of
our surfacetreatment.
