Physicochemical Standards
Physicochemical standards are essential reference materials used to ensure the accuracy and reliability of various analytical measurements in scientific research and industrial applications. This category includes a wide range of standards such as conductivity standards, electrochemistry standards, and ICP-OES/ICP-MS standards and reagents, which are critical for precise elemental analysis and conductivity measurements. pH buffer solutions and total organic/inorganic carbon reagents are vital for maintaining pH levels and measuring carbon content in samples. Standards from European Pharmacopoeia (EP), United States Pharmacopoeia (USP), and other pharmacopoeias provide benchmarks for pharmaceutical quality control. Additional standards like turbidity, density, refractometry, and viscosity standards ensure accurate physical property measurements. Specialized standards, such as those for wine, dairy, and petrochemical industries, support quality control and regulatory compliance in specific sectors. These physicochemical standards play a crucial role in ensuring the validity and reproducibility of experimental results, supporting a wide range of applications from environmental monitoring to pharmaceutical testing and materials science.
