Water and Residual Moisture Analysis at APM

APM, an analytical laboratory in Rivarolo Canavese, provides solutions for determining water content and residual moisture in various sample types. We use advanced techniques such as coulometric titration according to Karl Fischer, a specific and sensitive method capable of detecting water concentrations from 1 part per million (ppm) up to 100%. This approach ensures accurate results even in complex contexts, supporting quality control and regulatory compliance needs.

Karl Fischer Coulometric Titration for Water Determination

The primary method used for residual moisture analysis is coulometric titration according to Karl Fischer, a highly sensitive and efficient technique for determining the amount of water present in samples. Karl Fischer titration is specifically designed for water, providing a linear response that allows for the measurement of concentrations ranging from 1 part per million (ppm) to 100% moisture. This method ensures high accuracy, essential for applications where moisture control is critical, such as in the treatment of solvents, oils, fats, hydrocarbons, rubber, and plastics.

The principle of Karl Fischer titration is based on a chemical reaction between water and the Karl Fischer reagent, which allows the determination of the water content in a sample. This technique is adaptable to a wide range of materials, both liquid and solid, and is particularly useful for analyzing samples with very low or high moisture content.

International Standards and Reference Regulations

Moisture and water content analyses in materials are performed following strict international standards, ensuring accuracy and reliability:

ASTM D6304: An international standard that defines the titration method for determining water content in materials.
ISO 15512: : A global regulation that establishes guidelines for determining moisture content in plastic and polymeric materials.

These standards ensure that analyses meet the required industrial quality and precision criteria, guaranteeing compliance with current regulations for tested materials.

Applications of Water and Residual Moisture Analysis

The analysis of residual moisture and water is essential in various industrial sectors, including:

Solvents

The presence of water in solvents can alter their reactivity and reduce the efficiency of chemical processes. Determining moisture content is crucial to ensure the purity and quality of solvents used in various industrial applications.

Oils and Fats

In the lubrication and automotive sectors, the amount of water in oils and fats is a key factor for the performance and longevity of components. Excess moisture can accelerate the degradation of oils, negatively impacting the performance and lifespan of lubricants.

Hydrocarbons

Residual moisture in hydrocarbons, such as diesel and gasoline, can compromise fuel quality, affecting combustion and engine performance. Karl Fischer titration is vital for monitoring fuel quality.

Rubbers, Plastics, and Elastomers

The presence of moisture in materials such as rubbers, plastics, and elastomers can compromise their physical properties, including hardness, flexibility, and resistance to atmospheric agents. Controlling humidity is therefore essential to ensure the quality and functionality of these materials, especially in automotive and industrial applications.

Polymer Granules for Plastic Molding

Residual moisture in polymer granules is a critical factor in the plastic molding process. A high water content can negatively affect the final product's quality, causing molding defects and altering the material's properties.

Cooling Fluids

Cooling fluids, used in industrial machinery and automobiles, must be free of moisture to prevent corrosion, freezing, and reduced cooling efficiency. Moisture control in cooling fluids is essential to maintain system efficiency and longevity.

Automotive Components (Radiators, Condensers, Heat Exchangers)

In automotive components such as radiators, condensers, and heat exchangers, residual water can compromise efficiency and accelerate corrosion processes, reducing the lifespan of these parts. Monitoring moisture levels in these components' materials is crucial to ensuring their quality and long-term performance.
