On-site detection of the presence of four heavy metal contaminants in the soil! Anyone can easily determine it in a short time!
"OCTES" is a simple analysis kit for soil heavy metal contamination that allows for the easy analysis of hexavalent chromium, fluoride, boron, and lead. The analysis time has been reduced from 8 days to 1.5 hours. It does not require a power source or specialized analysis equipment, enabling anyone to easily determine in a short time whether heavy metals are present in the soil. Hexavalent chromium, fluoride, and boron are regulated by Japan's Soil Contamination Countermeasures Act with leaching concentration standards, and lead can be analyzed at a concentration 10 times higher than the leaching concentration standard. 【Features】 - Enables rapid response to contaminated soil cleanup, reducing construction time. - Allows for low-cost determination of soil contamination. - Reduces the need for temporary storage space for excavated soil, leading to lower construction costs. - Facilitates the subdivision of analysis, such as increasing survey frequency, which contributes to the reduction of soil requiring countermeasures. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Instructions】 ■ Mix the soil to be measured with water in a 1:10 ratio. ■ Place it on top of the soil leachate that has been shaken for 1 minute. ■ Soil particles are filtered out by the OCTES filter. ■ The water-absorbent resin absorbs the leachate. ■ The color development reagent in the water-absorbent resin reacts with heavy metals in the leachate, resulting in a color change. ■ Compare the color of the developed solution with a prepared color sample to determine the concentration. *For more details, please refer to the PDF document or feel free to contact us.
