Diffusion based membrane extraction devices are important analytical tools for sampling hydrophobic organic contaminants in water. This type of extraction eliminates the need for traditional grab sampling and reduces the time it takes to prepare samples for analysis. Solvents utilized in these extraction devices have typically included hexane or isooctane. These solvents are fairly toxic and pose a risk to analysts using the devices in the field as well as an environmental risk if the solvent happened to leak. It was of great interest to reduce the toxicity by employing ethanol as the solvent.Chapter 2: Materials and Methods 2. ... 200 Proof, Absolute, Anhydrous, ACS/ USP Grade), methanol (Pharmco-AAPER, Absolute, General use HPLC-UV Grade, Reagent Grade ACS/NF), ...
