Agilent 240Z / 280Z is a modern generation of atomic absorption spectrometers with electrothermal atomization and graphite cuvette.
AAC 240Z/280Z presuppose the installation of four and eight lamps, respectively. The lamps are selected automatically by means of a low-inertia mirror.
Agilent 240Z/280Z atomic absorption spectrometers confidently demonstrate the highest sensitivity and accuracy in the field of atomic spectrometry. Zeeman background correction and a constant temperature zone in the GTA120 Zeeman graphite furnace, as well as intuitive Windows-based software, provide excellent performance with easy operation.
