Wakopak® Wakosil® 5TMS

Wakopak® Wakosil® 5TMS is a HPLC column using revers-phase packing agent composed of trimethylsilyl groups (TMS) chemically bonded to silica gel. The retention of hydrophobic compounds is less than that of butyl (C4).
Wakopak® Wakosil® 5TMS is effective when you want to quickly elute compound with a stronger retention that other reverse-phase packing agent cannot or when you cannot increase the ratio of organic solvents in the mobile phase. Wakopak® Wakosil® 5TMS is also used for simultaneous analysis of samples with a wide range of polarity.
