Our new inert LC column technology helps labs improve their analysis of metal-sensitive compounds. A premium inert coating applied to the stainless-steel surface of our LC columns reduces nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks. Combined with Restek’s selective stationary phases, these new inert LC columns are ideal for the analysis of metal-sensitive compounds.
Stationary Phase Category: C18, octadecylsilane (L1)
Ligand Type: End-capped C18
Particle: 1.8 µm or 2.7 µm superficially porous particle (SPP or “core-shell” particle) silica
Pore Size: 90 Å
Carbon Load: 9% (1.8 µm), 7% (2.7 µm)
End-Cap: yes
Surface Area: 125 m2/g (1.8 µm) or 130 m2/g (2.7 µm)
Recommended Usage:
pH Range: 2.08.0
Maximum Temperature: 80 °C
Maximum Pressure: 1034 bar/15,000 psi* (1.8 ?m), 600 bar/8700 psi (2.7 ?m)
*For maximum lifetime, recommended maximum pressure for 1.8 ?m particles is 830 bar/12,000 psi.
Properties:
- Compatible with moderately acidic to neutral mobile phases (pH 28).
- Excellent data quality in food, environmental, bioanalytical, and other applications.
When to switch to a C18 column:
- You need a general-purpose column for reversed-phase chromatography.
- You need to increase retention of hydrophobic compounds.
