MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641029761 A) filed by Dr. Viswanath Kontu, Hyderabad, Telangana, on March 12, for 'modular multi-element analytical standard system based on chemical compatibility and method for preparation thereof.'
Inventor(s) include Dr. Viswanath Kontu.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A Modular Multi-Element Reference Standard System And Method Of Preparation The present invention relates to a modular multi-element reference standard system and method for stabilizing inorganic elements for analytical calibration. The system comprises a primary core solution containing a first group of chemically compatible elements in a controlled acidic matrix, and one or more secondary companion solutions containing a second group of elements selected based on intrinsic chemical incompatibility with the first group. The segregation is determined by chemical compatibility criteria based on properties such as oxidation state stability, redox sensitivity, and hydrolysis tendency. The system employs tailored matrices, including fluoride-containing matrices for hydrolysing elements (e.g., Ti, Si) and mixed-acid matrices for redox-sensitive elements, to prevent precipitation and matrix degradation. This modular architecture ensures long-term stability and analytical accuracy for instruments such as ICP-OES and ICP-MS."
