HSPgel Columns for High Speed GPC Analysis
These columns provide accurate and precise molecular weight calculations in under 7 minutes!
- Fast, accurate and precise molecular weight determinations
- Increase sample throughput
- Greatly decrease solvent consumption and disposal
Styragel Columns for Polymer Characterization Designed specifically for polymer characterization, the Styragel® columns are grouped into the HR series for low-to-mid molecular weight samples, the HT series for high-temperature applications, and the HMW series for high molecular weight samples. Specifically controlled styrene divinylbenzene formulations provide reproducible performance in your GPC applications.
Ultrahydrogel SEC columns Packed with hydroxylated polymethacrylate-based gel, Waters Ultrahydrogel™ SEC columns are ideal for the analysis of aqueous-soluble samples, such as oligomers; oligosaccharides; polysaccharides; and cationic, anionic, and amphoteric polymers. Measuring 7.8 mm x 300 mm, these high-resolution columns offer many advantages over conventional aqueous SEC columns, such as:
- A wide pH range (2–12)
- Compatibility with high concentrations of organic solvents (up to 20% organic, 50% organic if the mobile phase is introduced by gradient)
- Greater flexibility for the mobile phase
- Minimal non-size exclusion effects
Envirogel High-Resolution GPC Cleanup Columns The Envirogel high-efficiency GPC cleanup columns are specifically designed to remove low volatility, high molecular weight interferences, such as lipids and natural resins, from environmental samples as specified in EPA Method 3640A*. In the past, the cleanup procedure for environmental samples was performed on low-efficiency GPC columns based on packing particle
