Physicochemical analysis is a branch of chemistry that focuses on studying the physical and chemical properties of substances. It involves analyzing various parameters such as pH, conductivity, viscosity, and thermal properties to understand the behavior of substances under different conditions and interactions. This type of analysis is commonly used in fields like environmental science, materials science, and biochemistry.

To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
Proximate analysis determines the basic chemical composition of a feed sample, focusing on moisture, crude protein, fat, fiber, and ash content. Weende analysis is a specific method of proximate analysis that focuses on determining the crude protein, fat, fiber, and nitrogen-free extract content of feed samples. In summary, while proximate analysis is a broader term, Weende analysis is a specific method within proximate analysis that focuses on certain components.
Quantitative analysis involves measuring and quantifying the amount or concentration of a compound, while qualitative analysis focuses on identifying the chemical composition or properties of the compound. Quantitative analysis provides numerical data, such as mass or concentration, while qualitative analysis provides information on the structure or characteristics of the compound. Both types of analysis are commonly used in chemistry to fully understand a compound's properties and behavior.
Preformulation studies involve the physicochemical characterization of a drug substance in preparation for formulation development. These studies help in understanding the drug's solubility, stability, compatibility with excipients, and other factors that can impact its formulation. Overall, preformulation studies provide critical information that guides the formulation process for drug development.

Physicochemical theory examines the physical and chemical processes underlying biological systems, providing a framework for understanding how organisms function at a molecular level. This understanding is crucial for studying evolutionary processes, as changes in the physical and chemical properties of molecules can drive genetic variation and adaptation over generations. In essence, physicochemical theory helps to elucidate the mechanisms by which evolution occurs at a molecular level.

The survismeter measures osmolarity by developing a standard calibration between PCI (Physicochemical indicators such as viscosity, surface tension, friccohesity) and known values of osmolarity of some molecule.
