  • Name: SPE Media
  • Id: BC001

Solid Phase Extraction (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 is spherical with a uniform particle size. They also have a high surface area and high density of functional groups on the particle surface.

Nano-Micro Uni series columns have advantages of higher loading and recovery, lower solvent usage, faster flow rate, more concentrated elution and reproducibility than those of the competitors. Nano-Micro’s advanced manufacturing facilities and instruments as well as reliable procedures of quality control ensure the quality and reproducibility of the products.

 

World’s only supplier of monodisperse SPE sorbents.

Recovery equal to or higher than globally known brand name SPE columns.

High quality SPE sorbents similar to those employed in chromatography.

Highest performance and consistent quality in SPE products
