Spectroscopy

The high- sensitivity graphite furnace GFA-7000 enables ultra-trace analysis according to the electrothermal atomisation principle. The digital temperature and gas flow control is a new feature and enables the optimisation of all set parameters for the target element , such as the actual temperature in the drying-, ashing- and atomisation stage as well as the heating rate.

• extraordinary graphite tube lifetime for long multi-element sequences
• flexible heating programs with up to 20 temperature steps for complex matrices
• sample enrichment for atomisation
• two gas connections for argon or nitrogen and an alternative gas
