TSK-Gel SuperSW capilaries columns

Advantages compare to classical SEC columns

• Sensitivity 300% higher
• Sample volume 75% smaller
• Analysis time and elution buffer volume 50% reduced
• Efficiency 30% higher
• Theorical plates number: ≥ 30 000

High performance SEC columns. The small particle size (4 µm) ensure short analysis time with very high resolution.

Tosoh Bioscience TSK-GEL PW, PWxl, PWxlCP
Polymer based

These polymeric (polymethacrylate) columns are ideal for industrial polymers, oligosaccharides, nucleic acids and small viruses using aqueous buffer or salt solutions as mobile phase. The PWxl-CP columns are developed to facilitate SEC separation of cationic polymer under low salt conditions.

• Hydrophilic, rigid, spherical porous methacrylate beads 
• Excellent chemical  (pH 2 -- 12, 50% organic solvant) and  mechanical stability
• Temperature up to  80°C (50°C for TSK-Gel G-DNA-PW)
• Wide separation range up to  8 x 106 Da for linear polymers
• Available in analytical, semi-preparative and preparative stainless steel columns TSK-Gel
