The Buck Scientific 220
Graphite Furnace AA package includes
the Buck 210VGP with Graphite furnace and 40 position auto sampler with
8 standard positions.
A rear mounted furnace saves precious bench space while heating tubes
2,800 degrees Celcius in 1.5 seconds.
The 40 position autosampler measures the exact sample size each and
every time for great reproducibility.
With the Buck Scientific Graphite Furnace package you also get an Argon
regulator, Matrix Modifier kit, Buck Analyst software and 3 Hollow
cathode lamps and standards.
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 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.
