Particle Analysis

• Capable of measuring particle sizes from below 1 nm to 10 µm.
• Can also measure the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate.
• Multi-Angle Dynamic Light Scattering (MADLS) scheme for absolute confidence in particle and molecular size distribution analysis
• Non-Invasive Back-Scatter (NIBS) optics for versatile, high sensitivity, particle and molecular size measurements
• Optical filter wheel with fluorescence filter to allow measurement of fluorescent samples without impairing overall system sensitivity.  Also includes polarization filters for DDLS measurements
• Capillary cell for low volume measurements (down to 3uL)

The system has two sample dispersion units: 

• The Hydro EV is a flexible volume wet dispersion unit that can be used with standard laboratory glassware. It is suitable for a wide variety of dispersant volumes and particle size ranges.
• The Aero S is a state-of-the-art dry powder dispersion unit. It is modular in design, meaning that it is easily configured for different applications.

• Permits low surface area measurements without requiring krypton by essentially eliminating free-space error, the limiting factor in typical static volumetric systems

• Accelerates delivery of the analysis gas because sample uptake controls the rate at which the gas is delivered to the sample. This results in a surface area analyzer that is as fast as the physics of adsorption allows

• The use of a servo valve to control the rate of gas flow into the sample tube assures accurate attainment of target pressures without pressure overshoot
