Measuring the Sub-Nanometer Range with the pUNk
16 Feb 2017This application note describes how the pUNk dynamic light scattering (DLS) system can be used to detect particles of less than 1nm in size. Here, the pUNk DSl system is easily able to detect the presence of caffeine and provide an accurate estimate of the size and weight of the molecule.

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.
