Why Upgrade from Traditional Silica C18 to Polymeric HLB?
| Performance Feature | Polymeric HLB Cartridges | Traditional Silica C18 SPE Cartridges |
| Sorbent Matrix | Water-wettable DVB-N-vinylpyrrolidone | Silica-based octadecyl-modified (C18) |
| Bed Drying Resistance | High (Recovery unaffected if bed dries out) | Poor (Drying leads to dramatic recovery drop) |
| pH Stability Range | pH 1 – 14 (Stable under extreme conditions) | pH 2 – 8 (Silica dissolves/hydrolyzes outside) |
| Retention Spectrum | Acidic, Neutral, and Basic Analytes | Non-polar / Hydrophobic Analytes only |
| Adsorption Capacity | 2x – 3x higher than silica-based sorbents | Standard capacity |
