An autotitrator allows the measurement of zeta-potential and size distributions while adjusting the pH-value. Particle size is limited from 0.3 nm to 10 Вµm. 8 INTRODUCTION TO MOLECULAR WEIGHT MEASUREMENT Measuring molecular weight How is molecular weight measured using SLS The Zetasizer Nano. Scattering is detected at 13В° and 173В° in a temperature range of 0вЊ to 90 вЊ. Via dynamic light scattering the particle size and the zeta potential of nanoparticle dispersions can be determined.

Temperature control from 20-50 вЊ and a syringe pump allow a precise and reproducible analysis. With built in fluorescence filters (500 nm and 650 nm) it is possible to track fluorescent particles as well as non-fluorescent particles in solution. Non-invasive technique, giving information on the. Why Light Scattering The scattering intensity is a function of the molecular weight and concentration. Two laser modules with wavelengths of 642 nm and 488 nm allow tailored measurements depending of the particle size and material. Malvern Instruments & the Zetasizer Nano. Size distributions as well as nanoparticle concentrations of aqueous highly diluted dispersions can be determined. By utilizing different measurement chambers, the volume of the dispersion and the amount of sample can be adjusted. With different dispersion-units, particles can be dispersed in air, water and solvents. Particles with sizes ranging from 10 nm to 3.5 mm can be analyzed.

ZS zetasizer system (Malvern Instruments, Worcestershire, United Kingdom). With the Mastersizer 3000 the particle size can be determined by utilization of the SLS technique. Static and dynamic light scattering (SLS and DLS, respectively) can be used. The main application is in ultracentrifugation where gradients allow the precise fractionation of particle samples.

Dr Thomas Glen, an expert in SEM and TEM, is dedicated to supporting other scientists to using this facility.Binary mixtures of various solvents can be fabricated using this device. A programme of outreach and training is making this facility available to academic and industrial researchers UK-wide. The availability of this combined suite of instruments is transforming the ability of soft matter scientists to see inside their samples routinely. As a technique, cryo-SEM-FIB is so new that we know of only two current instruments in the UK, neither of which is dedicated to the study of soft matter. The SLS technique requires the system to be sensitive and exceptionally stable, so the Zetasizer has been designed to meet these criteria. This not only allows the user to expose desired sections at will, but also to build up a complete 3D picture (literally) by imaging the sample section by section to a resolution of 10 nm (100 times the size of atoms). (Zetasizer Nano ZSP, Malvern, UK) was used to determine the particle size distributions of the virgin and recycled PA12 powders.

FIB is a powerful technique that uses a focused beam of charged atoms (ions) to cut and section specimens very accurately inside the SEM. Selective laser sintering (SLS) AM machines is a form of PBF technology, which was introduced by Carl Deckard for. Malvern Zetasizer Nano series Manual Online: The Zetasizer Nano Range.

The University of Edinburgh has been awarded EPSRC funding to purchase a cryo-SEM-FIB, housed in the School of Physics & Astronomy.
