Shimadzu Shim-pack UC Series SFC Columns

Shim-pack™ UC Series

Fully Porous Silica Particle Based Columns for Supercritical Fluid Chromatography (SFC)

• The Shim-pack UC series columns offer a wide variety of stationary phases for separating all sorts of compounds using the unique characteristics of supercritical fluid chromatography (SFC).
• The series includes twenty kinds of packing materials and a wide range of particle and columns sizes that can be selected based on the purpose of analysis.

Retention Behavior of Respective Columns

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 also 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. The figure below shows how retention behavior can vary significantly depending on the type of stationary phase used when analyzing typical acidic, neutral, or basic compounds. Stronger retention can be achieved by selecting a stationary phase expected to interact with the target compound
