Standard THGA Graphite Tubes w/End Caps
Standard
THGA Graphite
Tubes with End Caps
For improved characteristic mass with
volatile and medium refractory elements such as
Ag, As, Cd, Co, Cr, Cu, Pb, Se and Tl, the THGA graphite tubes with
end caps are recommended. Note: THGA graphite tubes with end caps
are not recommended for refractory elements such as V or Ba.
■
Improved detection limits for volatile and medium refractory elements
■
Faster drying for complex matrices due to enlarged dosing hole

Our exclusive design
ensures even heating over
the entire length of the tube

Today’s analysts expect exceptional analytical performance from their
graphite furnace atomic absorption spectrometers. That performance
must be 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 subject to strict quality control by both the
instrument manufacturer and the graphite manufacturer.
PerkinElmer’s unique, transversely-heated graphite tube includes an
integrated platform. The exceptionally uniform temperature distribution
obtained with transverse heating significantly reduces or eliminates
condensation of the sample matrix components and “memory” effects,
and improves the atomization efficiency for refractory elements.
