The innovative multi-pore technology is now also available in 3, 4 and 6 micron TSKgel SuperMultiporeHZ columns. Three columns, varying in linear range, are available. The base material of each TSKgel SuperMultiporeHZ column is poly(styrene/divinylbenzene). Particles in TSKgel SuperMultiporeHZ columns are mono-disperse in size and exhibit a broad range of pore sizes. Each particle, by design, has an extended linear calibration curve, thereby greatly diminishing chromatograms with inflection points. GPC chromatograms without inflection points . . . it will take some getting used to.
The TSKgel HXL column line consists of eight columns with different pore sizes, TSKgel G1000HXL through TSKgel G7000HXL, and three columns with an extended linear range of the calibration curve, TSKgel GMHXL , TSKgel GMHXL-L and TSKgel MultiporeHXL-M. Main characteristics are: ultra-low sample adsorption, i.e., the columns show true size exclusion behavior for most polymers, maximum operating temperature for TSKgel Hxl-type columns is 60°C for G1000HXL , G2000HXL , G2500HXL and G3000HXL , and 80°C for the remaining columns in the product line. See TSKgel HHR HT columns for operating temperatures of 140°C, the columns are shipped in THF, which can be exchanged for a limited number of organic solvents. TSKgel HXL-type columns are conventional GPC columns with column dimensions of 7.8mm ID x 30cm.
