BUCK SCIENTIFIC - 220GF Atomic Absorption Graphite Furnace Package

Our graphite furnace package includes:

1)    Buck 210VGP Atomic absorption spectrophotometer 

2)    Graphite furnace atomizer for PPB detection levels

2)    40-position Auto sampler with 8 Standard Positions

3)   10 pack of graphite tubes

Details:

Our rear mounted furnace saves precious bench space while heating tubes 2,800 degrees C in 1.5 seconds.  The upgrade to Graphite furnace allows you to use less sample, get PPB detection limits, and fully automate your analysis.

Our 40 position auto sampler measures the exact sample size each and every time, for outstanding reproducibility.

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 2800°C in 1.5 seconds! 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 multi-step 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 auto-sampler 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.
