Polysiloxane Based Stationary Phases
Polysiloxanes are most common stationary phases for general separations. They are relatively stable, robust and versatile to wide range of applications. Different functional groups substitutes replace the methyl group on silicon atom, which characterizes the polarity of polysiloxane. Carefully controlling the polymer synthesis, capillary surface treatment and other manufacturing processes can control the column characteristics, such as polarity, retention, efficiency, inertness and repeatability of column performance to v ery tight w indows.

AB Builtin-Guard Column
AB Builtin-Guard column is combination of a AbelBonded® column with a built-in Abel-made guard column. The first 5-meter or 10-meter is part of the AB Builtin-Guard column. The guard column is just deactivated with no coated stationary phase. The single continuous piece avoids the problems of installation hassles, peak shape problems, and leaks associated with unions. Difficult samples, such as pesticides or drugs, can be analyzed without any undesirable contributions from the unions.
