| SILICA BASED SORBENTS | TECHNICAL SPECIFICATIONS
| FEATURES |
| ChromPACK C18-ne | Average partical size: 50 μm Silica base: spherical | * Non-endcapped bonded phasethat enables the silica surface to be more active
|
| Pore size: 60 Å; Endcapped: no Carbon | *Moderately nonpolar and polar secondary interactions |
| Carbon (C%): 17% | * Enhanced the retention of polar and basic compounds than C18 |
| ChromPACK C18 | Average partical size: 50 μm Silica base: spherical Pore size: 60 Å Endcapped: no Carbon Carbon (C%): 17% | * Organic anlalytes extraction: C18 has the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices, when the compounds of interest vaty widely in structure |
| | | * Desalting: When analyzing small to intermediatemolecules, ChromPACK C18 can be used for desalting aqueous matrices prior to ion exchange |
| ChromPACK C8 | Average partical size: 50 μm Silica base: Irregular | * Both normal and reversed-phase chromatography |
| Pore size: 60 Å | * Less polar compared to silica and less hydrophobic compared to C18 and C8 |
| Endcapped: Yes Carbon (C%): 11% | * Usually used to extract acidic, neutral and basic compounds from aqueous solutions |
| ChromPACK NH2 | Average partical size: 50 μm | * Aminopropyl phase,both hydrogen bonding and anion exchange |
| | Silica base: Irregular Pore size: 60 Å | * Weaker anion exchanger retention of very strong anions such as sulfonic acids which may be retained irreversibly on SAX |
| | Endcapped: No Carbon (C%): 5.0% pKa: 9.8 | * Separate peptides, drugs and metabolites from physiological fluids, and extraction of mono-and polysaccharides, steroids,cholesterol and triglycerides |
| ChromPACK PSA | Average partical size: 50 μm | * Similar selectivity to NH2 |
| Silica base: Irregular Pore size: 60 Å Endcapped: No; Carbon (C%): 8.0% pKa: 10.1 and 10.9 | * Strong affinity and high capacity for removing fatty acids, organic acids,and some polar pigments sugars when conducting multi-residue pesticide analysis in foods |
| | * Excellent sorbent for chelation |
| ChromPACK PSA SAX | Average partical size: 50 μm; Silica base: Irregular; Pore size: 60 Å Endcapped: No; Carbon (C%): 6.0%; pKa: completely dissociated | * Strongest anion exchange sorbent because of its quaternary amine functional group * Positive charged, better retention of weaker anions such as carboxylic acidsthat may not retain strongly enough on PSA or NH2 |
| | | | * Activate the ion exchanger by conditioning it with appropriate bufers |
| ChromPACK SCX | Average partical size: 50 μm | * Strongest cation exchange sorbent because of its benzenesulfonic acid functional group |
| Silica base: Irregular | * Optimized for use in organic applications |
| Pore size: 60 Å; Endcapped: No; Carbon (C%): 6.0%; pKa: <1.0 | * Nonpolar character exhibited by benzene ring is useful to compounds with both cationic and nonpolar properties in aqueous solvent |
| ChromPACK SCX | Average partical size: 50 μm; Silica base: Irregular; Размер пор: 60 Å | * Strongest cation exchange sorbent because of its benzenesulfonic acid functional group |
| | Pore size: 60 Å; | * Optimized for use in organic applications |
| | Endcapped: No; Carbon (C%): 6.0%; pKa: <1.0 | * Nonpolar character exhibited by benzene ring is useful to compounds with both cationic and nonpolar properties in aqueous solvent |
