We will be attending Pittcon 2017 in Chicago, Illinois March 5th – 9th and once again we are pleased to feature a number of our recognized characterization experts who will be presenting a variety of short courses throughout the week.
Time is running out, so don’t miss out on the early bird deadline for discounted admission which ends on February 18th.
Below is a listing of our available short course offerings.
We look forward to seeing you in Chicago at one of our short courses and our Booth #2416.

Light Scattering Uses in Water and Environmental Issues – Ana Morfesis (#77)
Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic. Surface water treatment, water remediation and waste water treatment are critical issues in providing safe drinking water to an ever growing world population. One of the requirements for removing or inactivating particulate contaminants as well as biological parasites is to enhance the coagulation capabilities in water treatment facilities. Objectives of this short course are to discuss the role that light scattering, turbidity and zeta potential can play in optimizing water clarification.

Size, Molecular Weight and Zeta Potential Characterization of Nanomaterials – Ana Morfesis (#79)
The objectives of this course are to discuss Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA), Molecular Weight and zeta potential methods. DLS and NTA are versatile and non-destructive measurement techniques that are ideally suited as a metrology of choice for size, stability and identification of nanomaterial, protein molecules, aggregates and emulsions or suspensions in solution. We will also discuss electrophoretic mobility measurements and the importance of zeta potential in understanding interfacial behavior and the formulation of multi- component products. We will discuss; DLS and NTA, differences between these sizing methods, review theory, provide useful tips for sample preparation and analysis of measurement results, molecular weight, introduce micro-rheology and zeta potential.

Fundamentals of Particle Size Analysis with an Emphasis on Light Scattering Techniques – Alan Rawle & Ulf Nobbmann (#31)
A 1-day course that will bring newcomers to the particle sizing field up to speed on the basics (including terminology, international standards and math) of particle size analysis. The main techniques (sieves, sedimentation, electrozone sensing) will be covered but the main emphasis will be on light scattering techniques in particular dynamic light scattering (DLS; 1 – 1000 nm approx.) and laser diffraction (0.1 –3000 mm approx.)

Optical Rheology: Get G’ and G” at Higher Frequency – Ulf Nobbmann (#127)
This day course covers the principles of optical rheology. Dynamic Light Scattering (DLS) is widely used to obtain particle size. It can also detect the thermally induced Mean Square Displacement (MSD) of tracer particles. This MSD is converted into shear storage and loss modulus G’ and G” using the generalized Stokes-Einstein equation. DLS micro-rheology can thus probe short time dynamics of weakly structured solutions, complementary to traditional rotational rheology. This may for example be used to study the evolution of weak viscoelasticity at the onset of gelation. The different practical steps (tracer bead selection, size by DLS, zeta potential to check absence of interaction) are covered with examples. Details of micro-rheology include basics (principle of operation, math, caveats) and example applications in laboratory research.
Thursday, March 9, 2017 – 8:30 AM
This course covers principles of advanced detection in Gel Permeation Chromatography (GPC) & Size Exclusion Chromatography (SEC): Conventional chromatography relies solely on a concentration detector (RI, UV) to find Mw, Mn, PDI, %aggregation, by linking the elution to similar known standards. Universal Calibration avoids the need for similarity, exploiting the universal scaling of intrinsic viscosity. Light scattering provides the ‘absolute’ molecular weight directly, irrespective of the sample’s chemistry and structure. The different calibration techniques (conventional, universal, light scattering) will be covered with examples. The details of intrinsic viscosity and light scattering detection will include basics (principle of operation, math, caveats) and applications in real laboratory research and QA/QC scenarios.

Sampling for Particle Size Analysis – Alan Rawle (#32)
A ½-day course that will bring personnel in the particle sizing field up to speed on the basics and importance of sampling for particle size analysis. The course will deal with 2 main objectives – determination of the minimum mass required for any required precision and the calculation of the best fundamental sampling error (FSE) based on the mass used in any particle size determination. We will point out the major issues with sampling including delimitation errors and provide limited advice as to the recommended routes to take a reasonable sample and the dangers of taking limited or unrepresentative samples. The course is suited to users of all particle size analysis techniques from sieves to light scattering and there will be a practical exercise for attendees.
See you soon!
