A technology for conveniently and accurately quantifying the surface charge density of nanomaterials.
You can process dozens of samples in a single day! Individual quantification of strong acidic groups and weak acidic groups is also possible.
Introducing a technology for the simple and highly accurate quantification of surface charge sites in nanomaterials. Conventional surface charge site quantification techniques have faced challenges such as being time-consuming and labor-intensive, and the high cost of automatic titration devices. In this technology, the sample size is extremely small compared to titration methods, and it can be executed using only highly versatile equipment. Additionally, it allows for rapid (within 2 hours) and simple operations, achieving measurement accuracy comparable to titration methods. **Features** - The sample size is extremely small compared to titration methods (0.5 to 2.5 mg per run). - Can be executed using only highly versatile equipment (centrifuge and visible light spectrophotometer). - Allows for rapid (within 2 hours) and simple operations, achieving measurement accuracy comparable to titration methods. - Enables individual quantification of strong acidic sites (sulfuric ester groups) and weak acidic sites (carboxyl groups). - Dye adsorption is completed in 2 hours. *For more details, please refer to the PDF document or feel free to contact us.*
