Quantitative analysis based on optical properties comprehensively supports the quantitative analysis of fulvic acid and humic acid!
"Humic substances" refer to a group of substances that have undergone changes in molecular structure as a result of organic matter produced by photosynthesis passing through microbial loops and physical and chemical processes, resulting in yellow to brown coloration and specific fluorescent properties. Our company comprehensively addresses quantitative analysis of fulvic acid and humic acid in various samples, including aquatic humus, soil humus, and the content of fulvic acid in products. In addition, we respond to customer inquiries regarding tests for humus generation during biodegradation processes, and tracking tests of degradation processes using LC/MS. 【Classification of Humic Substances】 ■ Hydrophilic acids ■ Fulvic acid ■ Humic acid *For more details, please refer to the PDF materials or feel free to contact us.
