AQUEOUS COLUMNS
Polymer Laboratories IncOH is a rigid macroporous packing for aqueous GPC/SEC with an extremely hydrophilic polyhydroxyl surface, designed for the GPC/SEC analysis of a wide variety of water soluble polymers. Polymer Laboratories have extended this highly successful range of columns, as follows:
| Column | Application |
| Polymer Laboratories IncOH 30 | Analysis of low molecular weight water soluble polymers |
| Polymer Laboratories IncOH 8µm MIXED | Analysis of polydisperse polymers, providing resolution over a very wide range of MW |
| Polymer Laboratories IncOH 15µm | Analysis of very high MW polymers where shear degradation is a concern. |
Benefits of using the Polymer Laboratories IncOH range of GPC/SEC columns include:
- The Polymer Laboratories IncOH functionality enables most neutral hydrophilic polymers to be chromatographed simply by using pure water as the eluent
- This versatility means that Polymer Laboratories IncOH columns can be used to analyze a wide range of neutral, polar, anionic and cationic samples
- Even relatively hydrophobic polymers, including polyelectrolytes, can be chromatographed with the addition of methanol at concentrations of 5 to 50%
