  • Patent number: 11639920
    Abstract: A qualitative and quantitative heavy metal analysis device and, more particularly, a qualitative and quantitative heavy metal analysis device implemented by a rotary platform are provided. The rotary platform device includes a main injection part which is positioned near a rotating shaft of a rotary platform, wherein the main injection part is configured to receive a fluid sample containing heavy metals, a pH adjusting part configured to adjust pH of the fluid sample, a detecting part coated with a chelating agent configured to initiate a color reaction with heavy metals in the fluid sample by spreading the pH-adjusted fluid sample into the detecting part, and a ruler for measuring a spreading distance of the color reaction, wherein the fluid sample moves from the main injection part through the pH adjusting part to the detecting part by a rotation of the rotary platform device.
