Physico-chemical is a branch of science which examines organic or inorganic chemical systems which are in plain or mixed form by physical methods. By examining the relationships between the physical properties and the composition of a system, the nature of the interactions between the components of this system is determined.
Physicochemical analysis performed in advanced laboratories is a reliable method of investigating physicochemical systems. The principles of these analyzes date back to the late nineteenth century.
In physico-chemical analysis, different physical properties of systems, generally phase transition temperatures and other thermal properties (such as thermal conductivity, thermal capacity and thermal expansion), electrical properties (such as conductivity and dielectric permeability) and optical properties (refractive index and rotation) ). Furthermore, the rate of transformations occurring in a system, its dependence on the composition of the system and the density, viscosity and hardness values are determined.
X-ray diffraction analysis and microscopic metallography techniques are commonly used in physico-chemical analysis studies.
Physicochemical analysis is an important method for studying systems composed of two, three or more components, for example alloys, minerals, solutions, oxides, semiconductors, superconductors and organic compounds.
For example, the main physicochemical parameters taken into consideration in the investigation of surface waters are the pH value in the water samples, electrical conductivity, total dissolved solids, total suspended solids, turbidity and sodium. High dissolved solids and sodium values indicate that water is unsuitable for drinking purposes.
A number of standards considered in physicochemical analyzes performed in advanced laboratories are:
TSE CEN / TS 16800 Guidelines for validating physico-chemical analytical methods
TS 10308 ISO 11464 Soil quality - Pretreatment of samples for physical chemical analysis
TS EN ISO 18369-4 Optics - Eye-related - Contact lenses - Part 4: Physicochemical properties of contact lens materials
The application is received, the contract and then the product, vehicle and vehicles for which, what kind of service is determined exactly.
The necessary laboratory environment is prepared and the products, tools and instruments requested by the organization are tested by experts with the reference of the existing standards and measurements are made.
The data obtained as a result of meticulously completed tests, measurements and analyzes are evaluated and accredited approved reports are submitted by expert engineers.
