Description

General description

Guard Column for 7.8mm ID TSKgel GMH_HR-H(S) HT columns.

TSKgel HT (High Temperature) columns are for the analysis of organic-soluble polymers at temperatures up to 140°C and are shipped in o-dichlorobenzene (ODCB), which can be exchanged for 1-chloronaphthalene and trichlorobenzene. The TSKgel mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample. Shearing, which can be observed when analyzing ultra-high molar mass polymers on columns packed with 5 micron or smaller particles, can be overcome by using the TSKgel GMHhr-H(S) HT column, which is packed with 13 micron particles. The (S) is a reference to this shearing effect.

Physical form

ODCB can be exchanged by 1-chloronaphthalene and trichlorobenzene.
