Abstract
A one-piece solid phase extraction article to be used in solid phase extraction analysis, a filtration funnel comprising the one piece solid phase extraction article, and a method of use of the article. The article, device and method provide for improved analysis of hexane extractable material by eliminating the standard use of polar solvents to pre-condition the sorbent materials. The one-piece solid phase extraction article comprises water wettable monomeric phase type sorptive material embedded within a porous matrix. The water wettable monolithic polymeric sorptive material may be a hydrophilic polymeric gel, such as functionalized C-18 sorbent material, and the porous matrix may be fibrous matric, such as a glass fiber. The one-piece solid phase extraction article may further comprise one or more pre-filtration layers which do not contain the sorptive particles.
