Matrix Modifiers for
Graphite Furnace AA
PerkinElmer provides you with the
maximum performance and the
lowest possible detection limits with
our high-quality matrix modifiers.
PerkinElmer matrix modifiers thermally stabilize the analyte, allowing
higher pyrolysis temperatures to be used, reducing background
absorption, and eliminating potential interferences.
L’vov Platforms
The L’vov platform is a small plate of solid pyrocoated graphite that is
inserted into the graphite tube. It has a slight depression in the center,
which can accommodate up to 50 μL of solution. The function of the
L’vov platform is to isolate the sample from the tube walls to allow more
reproducible atomization of the sample through indirect heating. The
platform heats primarily by the radiation given off from the tube walls.
Sample vaporization and atomization occur after the tube reaches
a steady-state temperature.
Pyrocoated Graphite Tubes
with Integrated Platforms
Graphite tubes with integrated platforms
are machined from one piece of graphite
and are totally pyrocoated, providing
exceptional tube-to-tube reproducibility.
The spherically-shaped platform
accommodates up to 50 μL of sample.
Pyrocoated Graphite Tubes
with Integrated Platforms
■
Provide STPF conditions for volatile and nonvolatile refractory elements due
to the significantly higher heating rates of tube and platform, which can be
used for all elements
■
Offer an extra measure of convenience versus manually inserting a
separate platform
■
Provide longer life with many aggressive sample matrices, such as
concentrated acids
L’vov Platforms
Use of the L’vov platform provides:
■
Vaporization into a higher temperature gas atmosphere producing more free
atoms, which reduce interferences
■
Longer tube life because aggressive samples are only in contact with the
solid pyrolytic graphite platform
