Sensitive and accurate furnace AATechnical Overview Agilent's GTA 120 Graphite Furnace system has been designed to deliver: • High sensitivity • Excellent background correction, even with tough interferences and high background absorbances • High productivity • Reduced running costs • Ease-of-use. The GTA 120 is available as part of the 240Z or 280Z dedicated Zeeman systems, or as an accessory for the 240, 240FS and 280FS AA systems, where Deuterium background correction is used.

Outstanding furnace performance for challenging samples While atomizing the sample, the magnet operates at twice the mains frequency to accurately track the background signal. A three point polynomial interpolation is applied to the background signal to further improve the determination of the background and provide an 11-fold improvement in correction accuracy. Agilent’s integrated GTA 120 and Zeeman GTA 120 Graphite Tube Atomizers are best known for outstanding furnace performance, no matter how difficult the sample. Agilent’s furnace design is capable of reaching the high atomization temperatures...

Extended graphite tube lifetime The GTA 120 reduces running costs by minimizing argon consumption and extending graphite tube lifetimes. The two stage external gas flow in the furnace work head greatly extends tube lifetimes. Gas consumption can be reduced by up to 40% compared to other designs by using low flows at low temperatures, and high flows at high temperatures when the graphite tube needs maximum protection.
