Particle testing, aerospace industry

Filters, fuels, lubricants and other fluids along with ceramic coatings, and metals are just some of the materials that can be tested for the aerospace industry. 

For example, The particle size of metal powders plays a critical role in parts made from sintered metal. These parts perform very well under adverse conditions and thus are used in various components of rockets and other space exploration devices. Ceramic coatings are also materials that are used in the aerospace industry.

Particle testing, Agricultural Industry

Antibiotics and other medications are produced for livestock to prevent loss of animals, reduce spread of disease and increase reproduction. The same tests used for human pharmaceuticals are also used to test agricultural pharmaceuticals.

The particle size of animal feed has an effect on digestion, packaging, and handling. Powder flowability, bulk, tap and true density, as well as particle size distribution analysis all can provide benefits to animal feed manufacturers.

Particle testing, Automotive Industry

From coatings on car parts, ceramics in electrical systems, to quality of filters and more, there are numerous applications for particle characterization in the automotive industry.

Powder coating is a dry, powder material that is used as a finish on automotive parts and outer body. Particle size and characteristics of the powder material have a large impact on the final outcome of the coating. Analysis can determine flow, adhesion, durability and other factors.

Beauty and Cosmetic

Particle testing, Cosmetic Industry

PTL analyzes many different products in the beauty and cosmetic industry including make-up, moisturizers, powders, sunscreens and creams just to name a few. 

Moisturizers improve appearance, protect and hydration skin. the Most moisturizers are oil in water emulsions with additives to improve stability or provide additional benefits such as sun screening properties. Formulating oil in water emulsions often requires knowledge of both the size distribution of the dispersed phase and the charge on the surface of the droplets.

Particle testing, Ceramics Industry

Ceramics are Non-metallic and inorganic materials that are used extensively in all kinds of applications from everyday goods, to high technology. Ceramic materials are lightweight, durable, chemical and heat resistant leading to extensive uses in aerospace, construction, medicine, sports, and military goods to name a few.

Engineered ceramics are a significant part of commercial and military aircraft and were used in the space shuttle and its equipment. Transparent ceramic coatings embedded into the glass of windshields on airplanes conducts

Particle testing, Chemical Industry

Plastics can be evaluated for thermal properties such as melting point, glass transition temperature, and decomposition temperature. Knowing when a plastic will melt can aid in the design of production process or predict failure of a critical part. Determining the particle size of feed material in extrusion equipment ensures a uniform melt during the extrusion process.

Many chemicals are ground or milled. Determining the particle size before and after milling allows for milling efficiency, thus saving time and energy usage. Obtaining the desired particle size prevents batch rejection and subsequent reprocessing.

Particle testing, Environmental Industry

Particle size analysis is essential to air quality. Regulatory agencies use these values to determine compliance with air quality standards. Emission engineers can use the particle size distribution results to design air handling equipment such as scrubbers, cyclones, and baghouses to remove fugitive dust prior to release into the air.

Process water can be analyzed before and after filtration to evaluate filtering efficiency. Particle size distribution and concentration are used to determine the proper filter size for a water treatment system.

Food & Beverage

Particle testing, food and beverage industry

The taste and texture of foods depend largely on the particle size of the ingredients used to make them. Chocolate manufacturers characterize their products by what they term as “Mouth Feel”. If the particle size of the Cocoa used to make the chocolate is too coarse, the product may feel gritty. If it is too fine, the product may feel sticky. Particle size also affects the level of bitterness when tasted.

Milk is a combination of oil and water. Oil and water are not miscible and thus form an emulsion. Particle size analysis can determine the droplet size of the oil emulsion. Zeta potential of the emulsion system can be used to predict stability of the milk on the store shelf. This can indicate the effectiveness of the homogenization process, improve the milk’s consistency and increase shelf life stability.

Medical Device

Particle testing, Medical Device Industry

Foreign particulate matter on implants such as knee, hip, or breast implants can cause infections and other health risks. Determining the size of these particles can allow improvements in cleaning processes and quality control measures to ensure devices are safe and suitable for use.

Wear particles from artificial joints can be sized to evaluate if they will present a long-term adverse effect in the body. Large wear particles from an artificial joint can cause pain, inflammation and premature failure of the joint surface. To test particles, manufactures place the joint into a saline bath and then move it thousands of times in a simulated “stress test”. This saline is then submitted to PTL where we analyze the fluid for the particle size of wear and debris as well

Petrochemical, Oil and Gas

Particle testing, Petrochemical Oil and Gas Industry

Catalysts are used in the oil and gas industry to either remove harmful emissions or capture different desirable components from petroleum through refining. By determining the surface area and particle size of the catalyst, researchers can determine its effectiveness and whether or not the catalyst needs to be replenished.

Particles in oil can reduce lubrication effectiveness and result in product failure. If the size of the wear particles is determined, filtration equipment can be engineered to remove the contamination and increase oil and product life. Images from a Scanning Electron Microscope can show contamination particles that can allow engineers to determine the point source of the contamination or wearing parts before failure occurs.

Research Universities

Particle testing, Research Industry

Research universities turn to PTL for controlled and unbiased results and our diverse range of physical characterization equipment.

Depending on how a material is produced, particle size, shape and density can provide information on the material’s crystallization mechanism and control. Thermal analysis can provide information on melting point, glass transition or decomposition temperature to indicate if the material will fail under different environments.
