The multimedia graphite furnace visualization system in China can intuitively monitor the dynamic evolution of the sample solution during the drying, ashing, and burning processes inside the graphite tube. It is convenient to observe the optimal position and depth of the automatic sampler capillary injection needle entering the graphite tube, as well as the position of the platform inserted into the graphite tube, ensuring analysis accuracy and the lifespan of the graphite tube. It is also a training tool for *.
