Separation Methods Technologies, Inc. (SMT) products

Particle Size: 5 µm, Pore Size: 60Å, Length: 150 mm, I.D.: 4.6 mm. When silica is used as the stationary phase, the functional groups involved in separation are the surface silanols. However, metal impurities in silica may provide additional sites of interaction for solutes of interest. SMT uses high purity silica packing materials that are available in variety of particle and pore sizes. These columns have performed well in the separation of many polar compounds such as pesticides and organic acids.

Particle Size: 10 µm, Pore Size: 100Å, Length: 150 mm, I.D.: 4.6 mm. SMT manufactures ultra-stable cyanopropyl [CN] columns for normal and reversed-phase chromatographic separation modes. These columns have some special characteristics. When used in normal phase mode, with relatively nonpolar solvents, CN-stationary phase can separate many polar compounds just like silica. When used in reversed-phase mode, with relatively polar solvents, CN-stationary phase offers complimentary selectivity that may be unattainable with traditional reversed-phase packings such as C18 and C8.

Particle Size: 5 µm, Pore Size: 100Å, Length: 150 mm, I.D.: 4.6 mm. SMT-Diol columns are developed as an alternative for silica columns used in normal phase separation methods. The Diol [-OH] functional group is controlled, and as such, provides more reproducible separation when compared to separation on silanols [-OH] from bare silica surface. Furthermore, the hydrogen bonding on the OH functional group on Diol packing material is not as strong as that of bare silica. This results in a reduced interaction of polar compounds on the column. SMT-Diol can be used in normal and reversed-phase separation of pesticides, herbicides, pharmaceutical metabolites, polar natural products, proteins, peptides and other polar biomolecules.
