Graphite
Do not accept imitations
Graphite components offered by other companies often refer to the
PerkinElmer part, implying that these components are made from the same
material and provide equivalent performance. This is misleading, as these
imitation components are not made from the same base graphite material,
nor are they tested to the same demanding quality control specifications.
The different base graphite material will alter the temperature calibration,
the heating rates and the performance characteristics.
Rely on genuine
PerkinElmer graphite
Today’s analysts expect exceptional
analytical performance from their
graphite furnace atomic absorption
spectrometers. That performance
must be stable and reproducible
from day to day with respect to
sensitivity (characteristic mass),
accuracy and precision.
The graphite tube, the heart of the graphite furnace, plays a vital role
in the overall stability of an analysis. In order to assure stable analytical
conditions from one atomization cycle to the next, and from graphite
tube to graphite tube, all graphite parts — contacts, tubes and
platforms — must be under strict quality control by both the instrument
manufacturer and the graphite manufacturer. PerkinElmer graphite
components continue to set the industry standard for quality.
The proper performance, maintenance, and serviceability of your
graphite furnace system can be assured only through the use of
genuine, high-quality PerkinElmer graphite components.
