st9988 Sciex API 5000 LC-MS/MS from AB

  • A wide diameter intake orifice which improves sensitivity by flowing more ions into the vacuum chamber.
  • A QJet® ion guide that prefocuses the ions before they enter the vacuum chamber for higher sensitivity and signal-to-noise ratio.
  • Improved Q2 lenses reduce CAD gas leakage into the vacuum chamber and improve sensitivity and signal-to-noise ratio.
  • Higher quadrupole operating frequency, which improves ion transmission and increases sensitivity, especially for low ion masses.
  • Higher sensitivity in all RF/DC scan modes.
  • Scanning in a mass range of m/z 5-1250 in quadrupole mode.
  • Enhanced resolution at reduced scan speeds.

QJet™ Ion Guide Technology in this API 5000™ offers:

  • Greater flow of ions into the system for increased sensitivity.
  • More efficient separation of ions from non-charged particles and improved focusing of ions into the mass analyzer for improved signal to noise performance.
  • Easy access and no tools required for simple cleaning.
