End-Capped THGA Graphite Tubes with Advanced Platform, Pkg. 20

The new Advanced Platform design suspends the platform in the tube using three small pins in a triangular layout. This has the advantage of minimizing wall contact and reducing thermal conduction from the tube walls resulting in even and rapid heating almost exclusively from thermal radiation, an ideal 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. 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. Features and Benefits: Improved detection limits for volatile and medium refractory elements and Faster drying for complex matrices due to enlarged dosing hole. Even and rapid heating Improved sensitivity for some applications Improved batch to batch reliability Exclusive and patented design - only from PerkinElmer! NOTE: THGA graphite tubes with end caps are not recommended for refractory elements such as V or for Ba. 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.
