SFC chromatography column Shim-pack UC

When conducting analysis with the Nexera UC supercritical fluid chromatography system, because diffusion of the sample band in the mobile phase is high compared with liquid chromatography, separation behavior changes significantly depending on the types of columns used. Shim-pack UC-X series was designed with a variety of stationary phases, making it suitable for analysis of various compounds. Achieve high speed and high performance Shim-pack UC-X series offers various stationary phases suitable for the mobile phase of high diffusion and low-viscosity liquid carbon dioxide. Analysis time can be reduced at a high flow rate without impairing the separation performance. In addition, analysis speed, which is limited in HPLC, can be increased. Wide range of stationary phases meets diverse needs Shim-pack UC-X series was designed with eight types of stationary phases and sizes to meet diverse research and development needs. High durability and stable reproducibility Shim-pack UC-X series achieves high inertness for improved analysis precision and increased column durability. Its uniform silica surface and stable chemical modification also ensure high analysis reproducibility. Features A wide variety of stationary phases for separating all sorts of compounds Since the hydrophobicity of supercritical carbon dioxide is similar to hexane, the primary separation behavior of SFC is considered generally similar to the normal phase mode. Depending on the stationary phase selected, other interactions can occur, such as pi-pi interactions or electrostatic reactions similar to HPLC. All 20 column types can be used for compounds with approximately neutral polarity.
