5 Introduction to Graphite Furnace System：The graphite furnace atomization device is an electric heating atomization device, which is divided into two parts: a temperature control power supply and a graphite electric heating atomization device. After the atomization device is powered on, its temperature can reach up to nearly3000Degree can rapidly atomize the tested sample and retain it in the atomizer, resulting in significant spectral absorption and greatly improving the sensitivity of atomic absorption instruments. Widely used inpetrochemical industry Environmental monitoring, drinking water, food, hygiene, drug testing, non-ferrous metals, rock and mineral analysis and other fields.

characteristicLow sampling volume: Only sample solution is needed for a single sample measurement10-20μL；Easy to operate: The intelligent design adopts computer full process control, and the heating program at each stage can achieve step heating or slope heating. The on/off of the internal and external protective gases can be freely set. When the cooling water pressure is too low or the water temperature is too hot, it can automatically alarm and stop heating up.

High measurement accuracy: The device is designed with an internationally advanced light controlled heating system, which achieves automatic full power heating during the sample atomization stage, improves the sensitivity and precision of the sample, and can effectively eliminate interference from various residual elements.
