Abstract
In embodiments, a packing material for supported liquid extraction has a sorbent media that includes synthetic silica particles. In embodiments, the synthetic silica particles can have physical properties relating to one or more of particle surface area, shape, size, or porosity. In one embodiment, synthetic silica particles have a surface area less than about 30 m/g. In another embodiment, the synthetic silica particles have an approximately uniform particle shape. In further examples, synthetic silica particles have a particle size in a range of about 30-150 μm inclusive or greater than about 200 μm. In another embodiment, synthetic silica particles are arranged to have a pore size greater than about 500 Angstroms. In an embodiment, an apparatus for supported liquid extraction includes a container and a sorbent media that includes synthetic silica particles. In a further embodiment, a method for extracting target analytes through supported liquid extraction is provided.
