Raptor LC Columns

Restek Raptor LC Columns

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.
Column conditioning ensures consistent EtG/EtS Results

Ideal for bioanalytical applications like drug and metabolite analyses
Hightened selectivity and retention for compounds that are hard to resolve or elute early on C18 and other phenyl chemistries
Limits ionization suppression; allows MS_friendly mobile phases

Ideal for high-throughput LC-MS/MS applications with minimal sample prep
Well-balanced retention profile for better detection and integration of large, multiclass analyte lists
Sterically protected to endure low-pH mobile phases without sacrificing retention or peak quality
Part of Restek's Raptor™ LC column line featuring 2.7 and 5 μm SPP core-shell silica

Compatible with moderately acidic to neutral mobile phases (pH 2 – 8)
Excellent data quality in food, environmental, bioanalytical, and other applications
General purpose column for reversed phase chromatography
Increased retention of hydrophobic compounds

Reliably analyze a wide variety of polar analytes (acidic, basic, and neutral) without time-consuming derivatization or complex ion pairing
Switch between HILIC and ion-exchange retention modes with simple mobile phase changes and short equilibration times
2.7 μm Raptor core-shell particles provide UHPLC-like speed and efficiency on all makes and models of LC systems
Ideal for increasing sensitivity and selectivity in LC-MS analyses
Avoid complex sample preparation procedures for a fast and simple isocratic LC-MS/MS method for PFAS analysys
Analyze glyphosate without derivatization or ion pairing
