AA Duo

Double productivity without doubling the price

The AA Duo is the world's only atomic absorption spectrometer with true simultaneous operation of flame and graphite furnace. The Agilent AA Duo provides simultaneous operation of two permanently mounted atomizers from one central computer. Operation is more flexible, setup and changeover times are eliminated, and simultaneous operation doubles your productivity.
Two AA Duo packages are available. The 55 AA/240Z AA Duo package provides simultaneous operation of a 55 AA flame spectrometer and a 240Z AA Zeeman spectrometer with an integrated UltrAA lamp module. The Agilent 240 AA/280 AA Duo package provide simultaneous operation of an Agilent 240FS AA or 280FS AA flame spectrometer and a 240Z AA or 280Z AA Zeeman spectrometer with an integrated UltrAA lamp module.


  • Be more productive—Agilent AA Duo's simultaneous operation of flame/hydride and graphite furnace doubles your productivity.
  • Get more choice—Combine flame or hydride atomizers with either a deuterium or Zeeman-corrected graphite furnace.
  • Save time—Agilent AA Duo's dedicated atomizers eliminate setup and changeover times.
  • Analyze any sample—The Agilent AA Duo offers the widest linear dynamic range from sub parts-per-billion to percent levels.
  • Set and forget optimization—Each atomizer is aligned for immediate use and never needs re-alignment.
  • Speed up—Take advantage of the Agilent AA Fast Sequential technology, which provides the world's fastest flame AAS.
  • Minimize training—The Agilent AA Duo is controlled by Agilent's Worksheet Software, delivering rapid instrument set-up, easy operation, and simple method development for novice and expert users.
