The Q-Col range of GenSphere HPLC columns are manufactured using silica of exceptional purity.
It is a totally porous, perfectly spherical particle, without surface irregularities and having extremely low metals content (Al, Fe, Ti and Zn).
The elimination of micro-pores on the surface of the silica enables a perfectly reproducible porosity resulting in the absence of chromatographic problems often found with other packing materials.
Q-Col HPLC Columns are available in a complete range of chemistries enabling the chromatographer to perform analyses across a broad spectrum of columns.
