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 extracted.

The DryDisk® Separation Membrane was designed to replace conventional sodium sulfate in the drying of sample extracts. The DryDisk® is a hydrophobic membrane, consisting of a GORETEX ® process filtration media based on polytetrafluroethylene (PTFE). The hydrophobic property of the membrane allows the extracting solvent to pass through it, while retaining any water in the sample extract on the membrane’s surface.

Effective removal of residual water from organic solvents is critical to achieve optimal recoveries for water soluble compounds. Sodium sulfate has been the standard technique for removing residual water from solvent extracts for many years; however, it has several major drawbacks. Water soluble analytes in the residual water phase can become adsorbed in the sodium sulfate, leading to lower recoveries.

Pesticides, including insecticides, herbicides and fungicides are used extensively to increase agricultural yields. The total world usage of pesticides in 2007 was approximately 5.2 billion pounds with the US consuming approximately 22% of the total.1 The wide use of pesticides yields concern that drinking water sources will become contaminated, exposing the population to hazardous substances that may cause cancer.

US EPA Method 1664 for Hexane Extractable Material (HEM) or Oil and Grease has allowed use of solid phase extraction (SPE) instead of liquid-liquid extraction (LLE) with hexane since 2007 and this has been widely adopted in the US. SPE is an equivalent extraction technique to LLE and produces the same n-hexane extract. The extract, similar to LLE, may contain residual water that must be treated properly and removed from the n-hexane extract.

Analysis of the perfluorinated alkyl acids listed in EPA Method 537 along with fluorotelomeric alcohols and perfluorinated sulfonates were extracted using SPE (using ISOLUTE 101 500 mg/ 6 mL SDVB SPE columns) and analyzed on the LCMS 8045. Minimum Detection Limits(MDL) ranged from 0.69 to 3.25 ppt. Extraction recoveries were greater than 80% for all compounds, with surrogate recoveries within 10% of the true value.

Pesticides have gone far in increasing food supply, important in a world expecting to have 9.8 billion people by 2050. However, the mechanisms that make pesticides effective in eliminating pests can also cause harm to humans and animals. News stories continue to point to contamination through spills and exposure through the respiratory system.

Polychlorinated Biphenyls (PCB) are a worldwide contamination problem. They are extremely stable and as such, very long lived in the environment. The end result is that PCBs tend to bioaccumulate throughout the food chain and a great deal of research and regulations have been dedicated to their study.

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. Environmental contamination, ISOLUTE, PAH, Polyaromatic hydrocarbons, soil,

In this application note, a suite of neutral and list 1 pesticides in methylene chloride is evaporated using the Biotage® DryVap. Pesticides containing many different functional groups, including sulfur and phosphorus groups, halides, nitramines, atrazines, alcohol, and carbonyl groups were efficiently concentrated for GCMS analysis. This data indicates that the DryVap System is inert and effectively manages solvent evaporation without generating localized hot spots in the system.
