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

Method 525.2 describes the procedure to determine a full suite of low concentration semi-volatile organic compounds in drinking water using solid phase extraction (SPE) or liquid–solid extraction (LSE) techniques. The City of Fort Worth, Water Department implemented an automated SPE process for the analysis of semi-volatiles by EPA Method 525.2 using the Atlantic® C18 solid phase extraction disk. Ethyl acetate, methanol and water were used to condition the Atlantic C18 disk prior to the extraction step. The extraction solvents used were a 1:1 mixture of methylene chloride and ethyl acetate. Extracts were then analyzed by GC/MS using a splitless injection technique.

The second unregulated contaminant monitoring regulation (UCMR2) program was developed to monitor US drinking water sources for currently unregulated compounds. EPA Method 527 is categorized under List 1; Assessment Monitoring in the UCMR2 program. It focuses on a wide range of semi volatile organic contaminants including pesticides that were deferred during the first UCMR, flame retardants, and pyrethroid pesticides. This application for EPA Method 527 employs SPE with analysis by gas chromatography / mass spectrometry (GC/MS).

Method 508.1 is used to determine twenty-nine chlorinated
pesticides, three herbicides, and four organohalides in
ground water, drinking water, and water in any treatment
stage. The analytes are extracted from the water using a 47
mm C18 disk. The disk is extracted on the Horizon
Technology SPE-DEX® 4790 Automated Extraction
System using Ethyl Acetate and Methylene Chloride
(DCM). The extract is then dried and concentrated using
the Horizon Technology DryVap® with DryDisk®
technology. Final analysis is by GC/ECD.

Method 526 is a gas chromatography / mass spectrometry(GC/MS) method for the determination of selected semivolatile compounds in raw and finished drinking waters.This method efficiently extracts analytes using the SPEDEX® 4790 with an Atlantic® 47 mm polystyrene divinylbenzene (DVB) disk. The disk is extracted with using Ethyl Acetate (EtAc) and Methylene Chloride (DCM). The extract is then dried and concentrated using the DryVap® concentrator system coupled with DryDisk® technology to a final volume of 1.0 mL. Final analysis is done by GC/MS.

In postmortem cases, where drugs or pesticides have been used for
their poisonous properties, traditional matrices such as urine and
whole blood may be inappropriate for qualitative and quantitative
analysis. As the site of metabolism for most drugs and toxins, the
liver may provide more insight to cause of death than other bodily

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.
