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

Biphenyl (USP L11)

  • 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

ARC-18

  • 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

C18 (USP L1)

  • 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

Polar X

  • 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
