A selection of solid phase extraction cartridges, available in many sizes, shapes, and types of stationary phase. A typical solid phase extraction involves five basic steps. First, the cartridge is equilibrated with a non-polar or slightly polar solvent, which wets the surface and penetrates the bonded phase.
However, much like the Soxhlet extraction technique, this method also is very time-consuming. [48] Solid-phase template As described above, one benefit of immobilising the template molecule on a solid support such as glass beads is the easy removal of the MIPs from the template. Following a cold wash to remove unreacted monomers and low ...
Solid-phase microextraction – This is based on adsorption of analytes onto a polymer-coated fibre or cartridge. [7] The small sample size taken onto fibres means that analytes are usually desorbed directly into the GC, while the larger cartridges are usually placed in a TD tube and subjected to single-stage thermal desorption.
Solid-phase microextraction sampling. Solid phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid (), [1] which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase. [2]
Boom method (aka Boom nucleic acid extraction method) is a solid phase extraction method for isolating nucleic acid from a biological sample. This method is characterized by "absorbing the nucleic acids (NA) to the silica beads".

The cartridge consists of a permeable, open, macro-porous matrix, made of a microporous solid substrate, compatible with the extractant phase, and accessible from/to the external world. The replaceable microporous matrix is initially wetted with the extractant, exposing a thin liquid layer on its surface without obstructing the macro-pores.
