Unique Furnace Design :

The Model 220 GF accessory is for PPB level analyses by graphite furnace AA. This fully integrated design uses an innovative, unique technology in a compact powerful furnace module. The quick-mount design permits rapid changeover between furnace and flame heads.


The unique power supply in our furnace is capable of generating temperatures up to 3000°C in less than a second! This ultra-fast heating rate provides superior sensitivity in refractory elements and carbide-forming metals. The on-board firmware gives the analytical chemist full control of all aspects of the analysis. Gas flows (external, internal, mini-internal and auxiliary are standard), data collection (integrated, real-time, peak height or absorbance area) and electronic parameters for the hollow cathode lamps and the various background correction routines can all be programmed by the operator for maximum results.


The Stabilized-Temperature Graphite Furnace AA (STGFAAS) procedure insures the highest accuracy and reproducibility. The 210VGP can initiate multistep sequences with alternate gas purging for fully optimized STGFAAS.

System Integration:

The integration of the controlling software with the furnace module is comprehensive, and methods development time can easily be cut in half by using our protocols to refine an analytical method. The Model 220AS random-access autosampler will fully automate your analytical operations without the need for an external PC to control the system. By incorporating a sample ID table within the software, complete data handling can be done internally.


Dimensions: 16"H x 12"W x 6"D, Net Weight equal to or less than 38 lbs

Back-Mounted Microprocessor-Controlled, high-Frequency (2KHz) Graphite Furnace module with 3000ºC /second heating rate. Maximum Temperature 3000ºC.
