OIL AND FAT ANALYSIS

The determination of water content in oils and fats is essential for evaluating their quality and stability over time. Excessive water content can compromise the physical and chemical properties of these materials, as well as promote corrosion and degradation. Our laboratory performs this analysis using the Karl Fischer method, a precise and reliable test that accurately measures the moisture content in oil and fat samples, in compliance with international standards.

Kinematic viscosity is a fundamental parameter for determining the flow behavior of oils and fats at various temperatures. This property is crucial, for example, in the formulation of lubricants and motor oils, where incorrect viscosity can compromise product performance. Our state-of-the-art equipment allows for precise measurement using capillary viscometers, in accordance with reference standards.

The ash content and heavy metals in oils and fats are fundamental indicators of their purity and the presence of contaminants. Heavy metals such as lead, cadmium, mercury, and arsenic are highly toxic and must be monitored to ensure that finished products are safe and comply with environmental and health regulations. APM performs these analyses using advanced mass spectrometry techniques, ensuring precise and reliable results.

Capillary gas chromatography coupled with mass spectrometry (GC-MS) is one of the most advanced techniques for the chemical analysis of oil and fat components. This method allows for the identification and quantification of a wide range of chemical substances, such as hydrocarbons, additives, contaminants, and volatile organic compounds. Our laboratory conducts qualitative and quantitative analyses, providing a detailed profile of the compounds present in the sample, which is crucial to ensure quality and compliance with industry requirements.

Polycyclic aromatic hydrocarbons (PAHs) are hazardous chemicals that can contaminate oils and fats during production or use. The presence of these substances can be harmful to human health and the environment. APM performs specific tests to determine PAH levels in oils and fats, using advanced analysis techniques such as gas chromatography and mass spectrometry. These tests are essential to ensure that products are safe and compliant with environmental regulations.

Fourier transform infrared (FTIR) spectroscopy is a non-destructive technique used to analyze the chemical composition of oils and fats. This technique allows for the identification of functional groups and chemical structures of materials, providing detailed information about the properties and quality of the sample. FTIR is particularly useful for analyzing oxidative stability, the presence of additives, and other chemical characteristics that affect the material's performance.
