Orthogonal and Complementary Nanoparticle Characterization Techniques for Particle Measurement
10 Mar 2016How can I trust my data? This is a common concern for many researchers using particle measurement instrumentation. Is the data affected in any way by the measurement technology, or alternatively by the user during sample preparation or by the analysis parameters employed? To answer this question, the use of independent and orthogonal measurement techniques in order to provide confidence and measurement validation must be considered.

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters. Find the best particle characterization instruments in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Particle Size AnalysisParticle size analysis describes the size distributions from sub-nanometer to millimeter of particulate samples. Size is an important physical property and the technique is often utilized in a range of industries, such as chemical, environmental and agriculture.Data AcquisitionData acquisition refers to the collection and organization of information and data sets.NanoparticlesNanoparticles are between 1-100nm in size. Nanoparticles can be used for a wide variety of applications including biomedical, catalysis and electronics.
