ISOLUTE EPH SPE columns and associated methodologies have been optimised to efficiently fractionate EPHs into aliphatic and polycyclic aromatic (PAH) fractions. The principle is similar to the approach taken by the Massachusetts Department of Environmental Protection (MADEP) and TPH criteria working group (TPHCWG) methods. However, compared to these methods, the ISOLUTE EPH fractionation column has been significantly reduced in size and the sorbent has been optimised in order to reduce solvent volumes and provide an automation compatible fractionation column. Automation of the fractionation process has been achieved without carryover of PAHs into the aliphatic fraction.

The removal of interferences and sample concentration are
essential steps in trace level detection of pesticides, sheep
dips, herbicides and PCBs in river water, wastewaters and
trade effluents. The following methods were developed by
the Environment Agency National Laboratory Service facility
at Nottingham using the Biotage RapidTrace for automated
solid phase extraction and the TurboVap II for evaporation.
The procedures are UKAS accredited and can reach detection
limits of 0.001 ug/Litre for some compounds.

EPA methods 8260 & 8270 cover the analysis of polychlorinated
dibenzo-p-dioxins and polychlorinated dibenzofurans
in ground & surface waters. This also now includes
1,4-dioxane and PCBs. This application note will focus on
the automated SPE of the sample rather than the detection
which usually involves GCMS or LCMS. NB The columns
and reagents used for soils and sediment analysis differ to
ground water extraction.

Methylisothiazolinone (MI) is used in a variety of personal care products, such as sunscreens, lotions, cosmetics. MI is a cytotoxin and as a result there is concern because of sensitization and allergic reactions as well as cell and nerve damage. A percentage of the population is at risk from contact dermatitis when exposed to this compound at sufficient concentrations. This poster describes the use of ISOLUTE SLE+ for extraction of MI from sunscreen.
