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.

石墨管作为石墨炉的核心部件，在分析的整体稳定性方面发挥着至关重要的作用。为确保从一个原子化周期到下一个原子化周期，以及从一根石墨管到另一根石墨管都能维持稳定的分析条件，所有石墨部件，包括接触部件、石墨管以及平台，都必须同时接受仪器制造商和石墨制造商的严格质量把控。

PerkinElmer 的横向加热石墨管配备了一体化平台。横向加热方式所实现的温度分布极为均匀，这在很大程度上减少甚至消除了样品基质成分的冷凝现象以及“记忆”效应，同时提高了难熔元素的原子化效率。

这些石墨管适用于珀金埃尔默的以下型号仪器：PinAAcle 900T、PinAAcle 900Z、AAnalyst 600、AAnalyst 800、Model 4100ZL、Model 4110ZL、Model 5100ZL 以及 SIMAA 6000 塞曼原子吸收光谱仪 。
