This study shows that the SPE-DEX® 4790 Automated Extractor system can process water samples containing suspended particulate matter, up to 1000 mg, for the analysis of PAH’s. As PAH’s are found in both the dissolved and particulate phase of the water sample, it is important to be able to handle “whole” water samples such that the particulate matter in the water sample is retained and extracted with the SPE disk. This filtration method ensures that the PAH’s found in the dissolved phase, and those adsorbed onto the particulate matter are properly

This work demonstrates the performance of automated solid phase extraction (SPE) for the extraction of PAHs from surface water sampled from a nearby pond containing some particulate. An automated system (Biotage® Horizon 4790) with Atlantic® DVB disks, following the requirements of method EN 16691, was used.

This application note describes the automated solid phase extraction (SPE) and GC/MS analysis of whole water samples according to EN16691 for PAHs.
Method EN 16691 is a recently developed method that uses solid phase extraction to isolate organic compounds from 1 L of water using a divinylbenzene (DVB) solid phase extraction disk.

Polycyclic aromatic hydrocarbons (PAHs) can be found in a number of water types, such as drinking water, surface water, ground water and wastewater. There are serval types of extraction techniques that can be implemented to remove them from water for measurement including liquid-liquid extraction (LLE), continuous liquid-liquid extraction (CLLE) and solid phase extraction (SPE). With LLE and CLLE there is little selectivity within the methods for difficult matrices or other compound interferences.

This application note demontrates that the Biotage® fully automated extraction, drying and concentration systems used with the Atlantic™ HLB disk are capable of extracting PAH compounds from sea water.
Typical extraction times using the Biotage® Horizon 4790 range from 20 to 25 minutes while drying and concentration on the DryVap® with the DryDisk® took approximately 35 minutes.

This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.
