What are the naming conventions for Tosoh Bioscience RPLC columns?
The TSKgel designation is the company’s trademark for all liquid chromatography columns. The letters “ODS” stand for octadecylsilane or C18 bonded to a silica support material. The number 80 or 120 in the name denotes the pore size of the resin in Angstrom. For instance, the silica in TSKgel ODS-140HTP columns has a pore size of 140 Angstrom. The letters Tm or Ts refer to an endcapped column (minimal free silanol groups). The endcapping in Ts is more exhaustive than that found in the Tm products. Tosoh Bioscience also supplies octyl (C8), phenyl, cyano (CN) and trimethylsilane (C1) columns for RPLC. Example: TSKgel ODS-80Tm = C18 on silica with 80 angstrom pores, endcapped.
