For the most demanding analyses, these UltraClean THGA graphite tubes - delivering exceptionally low levels of contamination due to advanced high-temperature gas-phase cleaning procedures.

• Have the lowest possible contamination levels due to extensive high-temperature gas-phase cleaning procedures
• Are tested and specified for blank levels of Cr, Ni, V, Mo, Ti (<0.003 integrated absorbance units) and Na, Fe, Al, Si, Ca (<0.0005 integrated absorbance units)
• Engineered for special applications such as the determination of extremely low traces of Na, Ca, Fe, Cr and Ni in ultra-clean reagents used in the semiconductor industry, and ultra-trace analyses of environmental, clinical, or food samples

For the lowest possible detection limits, residual contaminant levels may not be low enough to meet your requirements. UltraClean graphite tubes offer unmatched analytical advantages for special applications such as the determination of extremely low traces of Na, Ca, Fe, Cr and Ni in ultra-clean reagents used in the semiconductor industry, and ultra-trace analyses of environmental, clinical, or food samples.

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