Achieving highest DLS resolution with MADLS July 06, 2018; Holiday Inn Orchard City Centre

Back

Light scattering is a fundamental analytical technique for the characterization of particulate materials and is most commonly applied to colloidal systems, nanoparticles and macromolecules in solution or dispersion to determine paticle size, molecular weight, or electrophoretic mobility. Different methods of ight scattering analysis provide a range of usefull information about your samples:

  • Dynamic Light Scattering (DLS) measures the size and size distribution of molecules and particles
  • Electrophorectic Light Scattering (ELS) measures the electrophoretic mobility of particles or molecules in dispersion or solution – this is often converted to a ‘zeta potential’

About the programmes

Programme 1: Achieving highest DLS resolution with MADLS

Time: 0830 - 1200

Dynamic light scattering (DLS) as a technique is known to have limitations in resolving different size populations within the same sample. Multi-angle dynamic light scattering (MADLS) uses the angular dependency of the scattered light to improve the resolution of the technique by combining the information obtained at the different angles and giving a single, higher resolution size distribution. MADLS results are primarily displayed as volume-weighted particle size distributions, but can also be converted to intensity (back-scattered weighted) and number particle size distributions allowing for even more information to be extracted.

See Malvern Panalytical's most advanced system for the measurement of particle and molecular size, particle charge and particle concentration, and represents the most intelligent and flexible instrument in the Zetasizer range.

  • This session is free for all! Come for this session and we will waive off the fee for the Zetaclass. 
  • Stay until the end of the Zetaclass for a free demo appointment and special discount for the Zetasizer Ultra
  • See it to believe it: you will get to interact with our speaker from the UK and see the demo unit!

Programme 2: ZetaClass

Time: 1300 - 1730

Dynamic and eletrophoretic light scattering techniques have emerged as one of the most popular characterization methods for studying the size and stability of particles in the submicron region down to below 1nm. It can be used to measure a varity of particles suspended in liquid, such as proteins, polymers, micelles, carbohydrates, nanoparticles, colloidal dispersions and emulsions. This workshop will describe both techniques in detail and is most suitable for all new and exisiting Zetasizer users, researchers and professionals.

  • Cost fee: $120 per person (Course includes training materials and refreshments)
  • Payment should be made before 30 June 2018

About the speaker: Dr Diogo Fernandes

Dr Diogo Fernandes has been awarded a doctoral degree in Materials Science from the University of Central Lancashire, where he explored different ways to synthesize and characterize several types of carbogenic nanomaterials. He has acquired knowledge and experience in dynamic and electrophoretic light scattering not only during his PhD degree, but also over the last 9 months when he joined Malvern Panalytical. Currently, he focuses on providing technical support to customers and collaborators on the Zetasizer range of products, with particular emphasis on nanomaterials-based colloidal systems.

Our partner

Malvern Panalytical was formed by the merger of Malvern Instruments Limited and PANalytical B.V. on 1st January 2017, has headquarters in both Almelo (the Netherlands), and in Malvern (UK), and employs over 2,000 people worldwide. The combined entity is a strong player and innovator in the materials characterization market and will leverage the strengths of the individual companies in their end markets, ranging from building materials to pharmaceuticals and from metals and mining to nanomaterials.
