Atomic absorption graphite furnace control system
It is used for atomic absorption analysis using flameless heating and is an important supporting equipment for AAS-4530F and AAS-4510F atomic absorption spectrophotometers. It is an instrument specially used to measure trace metal elements. It injects the sample to be tested into a graphite tube, and under the protection of inert gas, the sample is heated at different temperatures to remove the moisture in the sample through the drying stage and the ashing stage to remove matrix interference without losing the measured elements in the original sample. The atomization stage fully atomizes the element to be measured in the sample, allowing the content of the element to be measured in the sample to be measured sensitively and accurately. Afterwards, the residual sample left in the graphite tube is removed through a high-temperature cleaning stage.
