The Micromeritics ASAP 2020 machines are used to characterize the active and support surfaces of catalysts, to determine the surface areas of adsorbents, and to determine the porosity and gas (e.g. carbon dioxide) storage capacity of various nanomaterials (zeolites, MOFs, etc.). Materials with low surface areas such as ..
Mercury porosimetry characterizes a material´s porosity by applying pressure to a sample immersed in mercury. The pressure required to intrude mercury into the pores is inversely proportional to the size of the pores. The method provides information about the specific surface area and pore size distribution, total ..
Size, zeta potential and molecular weight measurement are possible in same system. Dynamic Light Scattering (DLS) is used to measure particle size and molecule size. This technique measures the diffusion of particles moving under Brownian motion, and converts this to size and a size distribution. Laser Doppler ..
Quartz Crystal Microbalance with dissipation monitoring can be used in surface science to characterize the formation of thin films (nm). Two parameters - frequency and dissipation - are monitored simultaneously, in real-time, as molecular layers form on the sensor surface.
