SCIEX iMethods for Pharma and BioPharma

Key benefits of BioBA Solution for Quantifying Insulin Glargine

  • Sample preparation – Increased efficiency with the included reagent kit, sample preparation SOP, and LC-MS/MS detail method
  • Maximized sensitivity – QTRAP® 6500 Increased ionization efficiency and heat transfer with the new IonDrive™ Turbo V source and Increased ion sampling efficiency and ruggedness with the new IonDrive™ QJet ion guide results in LOD of 25 pg/mL and LOQ of 50 pg/ML
  • Large linear dynamic range – Measurements tested from 50–100,000 pg/mL are linear with close to 5-orders of magnitude (r = 0.99961)
  • Wide mass range – Range of m/z 5 – 2000 provides versatility for large peptide quantitation
