Physicochemical analysis is a method that combines physical and chemical techniques to study the properties and behaviors of substances. It is used to evaluate the quality and composition of various substances, from natural products to industrial effluents. This method is crucial to ensure product authenticity, environmental safety and the development of new materials. [1]​.

It consists of measuring and interpreting parameters such as pH, temperature, pressure, conductivity and solubility, among others, to characterize a substance and its interactions.[2] This method is widely used in various fields, such as chemistry, materials science and environmental studies, to understand how substances behave under different conditions and how they interact with other substances.[1].

Determination of the elemental and molecular composition of a substance.

Measurement and analysis of properties such as density, viscosity, melting point and boiling point. [3]​.

Study of how a substance interacts with others, for example in chemical reactions.

Investigate the different physical states in which a substance can exist, such as solid, liquid and gas.

Physicochemical analysis has numerous practical applications in various fields:

Characterization of materials for their adaptation to specific applications, such as in the development of new polymers, ceramics or metals.

Evaluation of the environmental impact of contaminants and understanding their behavior in different ecosystems. [4]​.

Characterization of the properties of pharmacological substances to guarantee their quality and stability.

Analyze the composition and properties of food products to guarantee their safety and quality.

Identification and characterization of substances involved in criminal investigations.

Analysis of the chemical and physical properties of artifacts and materials to understand their origins and history.[5]​.
