Raptor EtG/EtS, 2.7 µm, 100 x 2.1 mm LC Column

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.

Stationary Phase Category: Proprietary
Ligand Type: Proprietary
Particle: 2.7 ?m superficially porous particle (SPP or “core-shell” particle) silica
Pore Size: 90 Å
Carbon Load: Proprietary
End-Cap: Proprietary
Surface Area: 130 m²/g

Recommended Usage:

Properties:

• Resolution of EtG and EtS from matrix interferences.
• Increased retention of EtG and EtS compared to traditional phases.

Switch to the Raptor EtG/EtS column when:

• Other columns can’t resolve EtG and EtS from matrix components.
• You need high-throughput EtG/EtS analysis.
• Low-level detection limits are desired.

Features & Benefits

• Proven performance for accurate, reliable ethyl glucuronide (EtG) and ethyl sulfate (EtS) analysis.
• Strong retention consistently resolves analytes from matrix interferences.
• Long column lifetime ensures consistent performance injection after injection.
• Fast, 4-minute, dilute-and-shoot LC-MS/MS analysis supports high sample throughput.
• Save time and increase certainty with Restek’s definitive EtG/EtS method and quality reference standards.
