Graphite tubes are mainly used in geological samples, environmental samples and biological samples. The principle is that the sample is injected into a graphite tube, the graphite tube as a resistance heater, electricity after the rapid rise in temperature, so that the sample atomization.The pyrolytic coating on the graphite tube can prevent the oxidation of the graphite tube so as to prolong the service life of the graphite tube. At the same time, the coating also prevents the sample from invading the graphite tube, thus increasing sensitivity and repeatability.
Graphite Tube Classification:
1.According to the heating method: longitudinal heating graphite tube, transverse heating graphite tube.
2.According to the performance: ordinary graphite tube (non-pyrolytic) suitable for low temperature (≤2000℃) atomized elements such as silver, cadmium, lead; Pyrolytic graphite tube is suitable for low, medium and high temperature (>2500℃) atomized elements; Platform graphite tube is suitable for medium and low temperature (≤2400℃) atomized elements.
