Graphite Furnace 4510GF

The JVLAB 4510GF graphite furnace is used for atomic absorption analysis in flameless heating mode and is an important supporting equipment for the 4510F atomic absorption spectrophotometer. It is an instrument specifically designed for the determination of trace metal elements. It injects the tested sample into a graphite tube and, under inert gas protection, heats it at different temperatures to remove moisture from the sample during the drying stage, remove matrix interference during the ashing stage, without losing the content of the tested element in the original sample. The atomization stage fully atomizes the tested element in the sample, allowing for sensitive and accurate determination of its content. The residual sample left in the graphite tube is removed during the high-temperature cleaning stage.
