Unique Furnace Design
The Model 220 GF accessory is the latest technology in 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.
Capabilities
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.
Methods
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.
Options and Accessories
Model 420 Continuous Flow Hydride
The Model 420 hydride accessory provides virtually instant access to PPT detect ability for hydride metals in a semi-automated, continuous flow system. Low level determinations of As, Se, Sb, Bi, Te, Sn, and Ge are easily performed. The cold vapor mercury model achieves trace level analysis.
Model 220AS Furnace Auto sampler
Complete system automation can be achieved using the Model 220AS Auto sampler. This fully programmable, random access system provides 40 sample cups and eight calibration/QC cups. It can also perform automatic matrix modifier additions and sample dilutions. Sample cups can be identified in the built-in table, and method development time can be reduced substantially.
Model 240 Flame Auto sampler
To enhance laboratory productivity, this 150 position auto sampler features a fast access rate for unattended operation. Users can program various dilution and sample volumes with automated spike addition. A high quality coating resists acids and bases. Full random access allows for complete flexibility.
AAnalyze™ Data Acquisition Software
Provides automated data collection via RS232C, conforming to all EPA protocols. Data handling capabilities include auto calibration, spike recoveries, drift corrections, and QC charting. Calibrations are performed using linear or polynomial regressions in a Windows®-based, easy to use format. Full report generation with calibration curves and QC chart printouts as well.
AA Accessories
Buck Scientific offers high quality hollow cathode lamps, and aqueous and organic standard solutions. For furnace operation, we offer matrix modifiers and buffers, plus three styles of graphite tubes. Buck has all the accessories and supplies needed for atomic absorption spectroscopy.
