Supercritical Fluid Chromatography (SFC) - Diol
Nacalai Tesque COSMOSIL 5Diol Analytical SFC Column, 5µm, 120Å, 2.1mm I.D. x 150mm Length, 1/Pk
Product Number: 18253-21
Less effect from ionic interaction
Supercritical Fluid Chromatography (SFC) has become more attractive because it offers some advantages over HPLC, such as high speed, unique selectivity and environmentally friendly separations. Many conventional normal-phase stationary phases, such as diol, amino and cyano, have been used for SFC applications. However, these phases present limitations for separations. COSMOSIL SFC Columns have been developed to enhance the capability of SFC separations.
Nacalai Tesque has developed columns specially designed for SFC in collaboration with Nacalai USA and Pfizer, Inc. Global R&D: COSMOSIL HP, PY (equivalent to 2-ethylpyridine) and Quinoline. In addition to these, our HPLC columns Cholester and PBr have been tested for use with SFC.
