4510GF Graphite Furnace

The 4510GF graphite furnace is used for atomic absorption analysis using flameless heating and is an important supporting equipment for the 4510F atomic absorption spectrophotometer. 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 content of the element in the sample is fully atomized in the atomization stage, so that the content of the element to be measured in the sample can be measured sensitively and accurately. The residual sample left in the graphite tube is removed through the high-temperature cleaning stage.
