Solid Phase Extraction (SPE) Disks
|
Solid phase extraction (SPE) disks are used commonly in large-volume sample preparation. These disks resemble the membranes used for filtration, but differ in that sorbent particles are embedded in an expanded PTFE network or fiberglass matrix. Solid phase extraction (SPE) disks are flat (usually 1-mm or less in thickness) with diameters ranging from 4 to 96 mm. Generally, the packing material comprises 60 to 90% of the total membrane weight. The small length-to-diameter ratio of and SPE disk enables higher flow rates and faster extractions than can be achieved with cartridges. For example, 1 liter of relatively clean water can pass through a 45-mm SPE disk in approximately 20 minutes, but may require one to two hours when using a 15 mm x 18 mm cartridge bed. Products & Services
Solid phase extraction (SPE) cartridges and discs are used to clean up a sample before using a chromatographic or other analytical method to quantify the amount of analyte(s) in the sample.
