Restek Raptor™ Biphenyl 90 Å HPLC Columns
Exceptional Selectivity for Aromatic and Structurally Related Compounds
The Restek Raptor™ Biphenyl 90 Å HPLC column series combines an advanced biphenyl stationary phase with Restek's 2.7 µm superficially porous (core-shell) particle technology to deliver exceptional chromatographic efficiency, outstanding peak shape, and unique selectivity for aromatic compounds. Designed for both conventional HPLC and UHPLC systems, these columns provide fast, highly reproducible separations while maintaining moderate operating backpressure.
Unlike traditional C18 stationary phases that rely primarily on hydrophobic interactions, the Raptor Biphenyl phase utilizes additional π-π interactions, dipole interactions, and steric (shape) selectivity. These complementary retention mechanisms significantly enhance the separation of structurally similar compounds, positional isomers, and conjugated aromatic molecules that are often difficult to resolve using conventional reversed-phase chromatography.
The proprietary bonded phase chemistry is highly stable, providing excellent reproducibility and long column lifetime for both routine quality control and demanding analytical method development.
Key Benefits
- Proprietary biphenyl stationary phase offering unique aromatic selectivity.
- Enhanced π-π interactions improve the resolution of aromatic analytes and closely related structural isomers.
- Excellent retention of moderately polar aromatic compounds without excessive hydrophobic retention.
- Outstanding peak symmetry for acidic, basic, and neutral compounds.
- High efficiency through 2.7 µm superficially porous particle technology.
- Fast analysis with reduced backpressure compared to fully porous sub-2 µm particles.
- Fully compatible with HPLC, UHPLC, and LC-MS/MS platforms.
- Robust performance suitable for high-throughput analytical laboratories.
- Excellent reproducibility from batch to batch and over extended column lifetime.

Typical Applications
The Raptor Biphenyl stationary phase is particularly advantageous whenever additional aromatic selectivity is required beyond the capabilities of conventional C18 columns.
Typical applications include:
- Pharmaceutical active ingredients (APIs)
- Pharmaceutical impurities and degradation products
- Stability-indicating methods
- Positional, structural, and stereoisomer separations
- Veterinary drug residue analysis
- Pesticide multi-residue methods
- Polycyclic aromatic hydrocarbons (PAHs)
- Phenolic compounds
- Flavonoids and other natural products
- Mycotoxins
- Clinical and forensic toxicology
- Environmental contaminants
- Food safety testing
Its unique selectivity frequently allows baseline separation of analytes that co-elute on standard C18 columns, reducing the need for complex gradient optimization or alternative chromatographic methods.
