Light Scattering University
The LSU Experience
LSU is the brainchild of Dr. Philip Wyatt, who wanted to instill in our customers more than just a passing reference to light scattering. The course demystifies light scattering and provides a unique opportunity to dive into your needs and applications with our expert instructors, connect with light scattering users from around the world, and gain a deeper understanding of your instrumentation and software. Over the past 30 years, the class has grown in its curriculum and its scope. It delves into the theory—and practice—of classical and dynamic light scattering through hands-on practice sessions, software exploration in the computer labs, lectures, and individual instruction. Attendees leave with the most up-to-date documentation, software and firmware versions, and tutorials that benefit everyone back home.
LSU not only reinforces concepts from the first installation training visit but also ensures the same level of knowledge and understanding is passed on to the newest users. The gold standard of education from our experienced LSU faculty gives everyone in the lab the right starting point and sets them up with the best foundation possible. In addition, LSU students discover advanced data processing methods and alternative analytical tools that they may not have been aware of and learn how their MALS and DLS data complements information from other techniques they are using in the lab. A LSU credit, inclusive of airfare, accommodations and most meals, is included for most North American customers who purchase one of our light scattering instruments. While you are here, we work you hard but feed you well—at a variety of Santa Barbara restaurants!
During LSU our students meet Dr. Wyatt, who not only gives an acclaimed Light Scattering Instrument Museum tour, but also delivers a great lecture colloquially referred to as the Dead Physicist’s Talk. There is ample time for our students to meet the people who invented the instruments, build the instruments, as well as those who service and support the instruments. By the time LSU ends, there’s no reason to hesitate to ask for help from someone specifically.

In addition to learning from the faculty, the students in each small cohort learn even more from each other. It’s the perfect opportunity to network, share questions or successes, and troubleshoot common problems. We’ve even introduced colleagues to each other who worked on different floors in the same company but had never met! LSU brings together users with a variety of applications, all of whom share a need for the robust macromolecular characterization afforded by light scattering.
Besides an educational opportunity nonpareil, LSU is a unique time for building rapport between Wyatt Technology and its customers. Not only do we have staff who have been at WTC for decades, but we have customers who have used our equipment that long. Friendships transcend jobs and equipment, and help make the LSU experience personal and meaningful, because we don’t just build instruments, we build relationships. We look forward to welcoming you to Santa Barbara—the American Riviera—sometime soon.

Outstanding!
Often described by participants as the best instrument user training they have ever attended, Light Scattering University (LSU) is an intensive three-day experience that combines hard work, good food and a friendly, relaxed atmosphere. LSU operates on two main campuses: at Wyatt Technology Headquarters in Santa Barbara, CA, USA, where attendees enjoy the famously comfortable and sunny Santa Barbara climate and at Wyatt Technology Europe in Dernbach, Germany, with easy access from much of Europe.
In Santa Barbara, LSU and DynaLSU are offered every month. In addition, LSU attendees may elect to add a fourth day for extra training on their Eclipse or Calypso instruments, according to our quarterly schedule, and Mobius training is offered as part of DynaLSU once per quarter.
In Dernbach, LSU is offered every month, and DynaLSU is offered every other month. LSU attendees in Dernbach may elect advanced training on the ViscoStar or Eclipse instruments according to the yearly schedule, including theory, installation, operation, and method development. Half the classes are offered in German.
For more details, please explore the LSU training dates in Santa Barbara and Germany.
Why attend?
LSU and DynaLSU are designed to get you up and running with your Wyatt instruments as quickly as possible. The syllabus includes light scattering theory and lots of hands-on work with light scattering instruments and ASTRA or DYNAMICS software. You'll also get an introduction to some of the advanced techniques, such as field-flow fractionation and composition-gradient light scattering. Pass the exams and you'll receive a Master of Light Scattering certificate, in Latin or Greek, guaranteed to impress your boss and coworkers!
Many trainees come away from LSU inspired with new ideas for how light scattering can solve some of their analytical challenges. One of the favorite aspects of LSU mentioned by attendees is the opportunity to meet and work with the scientists and engineers behind the products as well as support staff that they usually only speak with over the phone. Another highlight (available only in Santa Barbara) is the Light Scattering Museum tour, led by none other than Dr. Philip Wyatt, inventor and pioneer of MALS detectors.
DynaLSU is a comparable two-day course for users of DynaPro or Mobius instruments. Many Santa Barbara LSU attendees elect to add a fourth day for extra training on their Eclipse, ViscoStar or Calypso instruments. Dernbach attendees may elect advanced training on field flow fractionation, including theory, installation, operation, and method development. For more details, please explore the Light Scattering University training options.
It's personal.
The lessons are a combination of lectures, seminars, hands-on lab work, quizzes, and individual instruction based upon the background and applications of each student. With a low ratio of students per instructor, there is ample time for individual help and small group work.
Students are encouraged to bring their light scattering data files for individual consultations.
Schmooze!
Social time is also scheduled to allow the students to learn from each other and to interact with Wyatt staff in a relaxed atmosphere. We encourage all attendees to join the Light Scattering University Alumni group on LinkedIn, and keep in touch!
