SynChropak was the first commercial bonded silica of this type, followed by LIChrosorb DIOL and LiChrospher DIOL. Protein-Pak materials as well as Sl-Polyol are similar in surface composition. Recently a specifically pH-stabIIized, glycerol-bonded silica has been introduced on the market Zorbax Bio-Series 6F 250. The most popular are the TSK gel SW types which are thought to be bonded with a glycerol-ether moiety. On annealing from 400 to 823 K, the TSK gel SW 3000 showed a weight loss of ca. 15X while the carbon content was 7.3X, Indicating on oxygen-rich... [Pg.220]

Larger pore-sizes are available for most of these columns. Other column materials that can be used for SE-HPLC are the 1-125 and 1-250 material (Waters, Milford. MA), the LiChrospher diol series (Merck, Darmstadt, FRG) and the polymer-based TSK-PW series (Toyo Soda). The SynChropak GPC series are also sold as Aquapore OH (Brownlee, Santa Clara, CA). Most of these column supports are only available as packed columns the SynChrqiak GPC series is available as bulk support. The support pore volume ratios for the TSK and Superose supports are from refs 3 and 6, respectively, those for the Zorbax and the SynChropak supports are from the manufacturer. [Pg.94]
