PerkinElmer B0504033 Integrated Platform THGA Graphite Tubes, Pkg. 20

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. The tubes are compatible with PerkinElmer PinAAcle 900T, PinAAcle 900Z, AAnalyst 600, AAnalyst 800, Model 4100ZL, Model 4110ZL, Model 5100ZL, SIMAA 6000 Zeeman AA instruments.

石墨管作為石墨爐的核心部件，在分析的整體穩(wěn)定性方面發(fā)揮著至關(guān)重要的作用。為確保從一個原子化周期到下一個原子化周期，以及從一根石墨管到另一根石墨管都能維持穩(wěn)定的分析條件，所有石墨部件，包括接觸部件、石墨管以及平臺，都必須同時接受儀器制造商和石墨制造商的嚴(yán)格質(zhì)量把控。

PerkinElmer 的橫向加熱石墨管配備了一體化平臺。橫向加熱方式所實現(xiàn)的溫度分布極為均勻，這在很大程度上減少甚至消除了樣品基質(zhì)成分的冷凝現(xiàn)象以及“記憶”效應(yīng)，同時提高了難熔元素的原子化效率。

這些石墨管適用于珀金埃爾默的以下型號儀器：PinAAcle 900T、PinAAcle 900Z、AAnalyst 600、AAnalyst 800、Model 4100ZL、Model 4110ZL、Model 5100ZL 以及 SIMAA 6000 塞曼原子吸收光譜儀 。
