Gel Permeation Chromatography

TSKgel SuperAW-L GPC Guard Column, 7 μm, ID 4.6 mm x Length 3.5 cm

Suitable for the following columns:
  • TSKgel SuperAW2500
  • TSKgel SuperAW3000
  • TSKgel SuperAW4000

TSKgel SuperAW columns are composed of spherical, hydrophilic methacrylate beads. 

Unlike TSKgel PW/PWxl-type columns, which are stable up to 50% organic mixed with water, TSKgel SuperAW and Alpha-type columns are stable in a wide variety of organic solvents at concentrations up to 100%. Efficiency of all TSKgel SuperAW-type columns is maintained when changing solvents from water via acetonitrile, DMF, DMSO, THF to HFIP. 

TSKgel  SuperAW columns are used for high efficiency and high speed analysis of polymers that are soluble in polar organic solvents. Examples include cleansing gel in methanol, degree of saponification of polyvinylalcohol in HFIP, and sodium dodecylsulfate, polyimide, and cellulose derivatives in DMF with 10mmol/L LiBr. 

Mixed-bed TSKgel SuperAW Column:

The mixed-bed column, TSKgel SuperAWM-H, has an extended linear calibration range, and is suitable for samples with a broad MW distribution as well as samples with unknown molecular weight.
