PerkinElmer THGA Standard Graphite Tubes

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.
