GRAPHITE FURNACE
MAASMAN GRAPHITE FURNACE
AND L’VOV PLATFORMS FOR AAS
Graphite furnaces are intended for the use in Atomic Absorption
Spectroscopy to provide electrothermal atomization of samples
by heating them up to +3000
°C.
|
|
Special furnaces profile allows for achievement of homogeneous temperature distribution inside furnace.
PYROGRAPHITE COATING
Pyrographite coating allows for the determination of all elements used in atomic absorption with electrothermal atomization.
Furnaces are made from high purity graphite, therefore you do not face problems of cleaning furnaces from the traces of determined elements.
GRAPHITE FURNACE LIFETIMES
Number of working firings varies from 300 for elements with high atomization temperature (Al, Ni, Mo) to 1000 for highly volatile elements (Cd, Zn, Bi).

L’VOV’S PLATFORMS
L’vov platforms are made from pure pyrographite. The number of working firings for the platform is very high: from 1000 to 2000 firings.
The platform lifetime is even longer than an average furnace lifetime, therefore the cost of analysis is minimized. L’vov’ platforms practically do not decrease the internal opening, and the signal/noise ratio is not changed.
DIMENSIONS
Standard dimensions (length: 28 mm, diameters: external - 8 mm, internal – 6 mm) allow to use the furnaces in many types of analyzers. Under Customer’s request we can ship graphite furnaces of other dimension types.
The graphite furnaces are delivered in packages of 10 pieces with or without L’vov pyrocoated graphite platforms.
