General description

The TSKgel HHR column line consists of eight columns with different pore sizes, TSKgel G1000HHR through TSKgel G7000HHR, and five columns with an extended linear range of the calibration curve. All TSKgel HHR-type columns are shipped in THF, which can be exchanged for a much broader range of organic solvents than TSKgel HXL columns, although Hxl columns are more inert. The maximum operating temperature for most TSKgel HHR-type columns is 140°C, except for GMHHR columns, which can only be used up to 80°C. TSKgel HHR-type columns are conventional GPC columns with dimensions of 7.8mm ID x 30cm.

Use to protect G1000HHR to G4000HHR and GMHHR-L columns.


THF can be replaced with acetone, ethanol, quinoline, benzene, o-dichlorobenzene, ethyl acetate, dodecane, FC-113, carbon tetrachloride, dichloromethane, dichloroethane, trichloroethane, n-hexane, cyclohexane, xylene, tetrahydrofuran, chloroform, 1,4-dioxane, hexafluoroisopropanol, toluene, 1-chloronaphthalene, dimethylaceto acetamide, methyl ethyl ketone, trichlorobenzene, m-cresol, dimethylformamide, methylpyrrolidone, o-chlorophenol/chloroform, dimethyl sulfoxide, pyridine
