SPE is a column chromatographic analysis
process bearing much similarity to high performance liquid chromatography
(HPLC) in the mechanism of separation and choice of reagents and solvents.
In the past, monodisperse sorbents are only
used in high-end chromatography and analysis columns. Under optical microscope,
the first generation silica sorbents are irregular in shape and the second
generation spherical polymer particles are broad in size distribution. The new
generation Uni series SPE sorbents by Nano-Micro Tech is spherical with a
uniform particle size. They also have a high surface area and high density of
functional groups on the particle surface.
