Getting expert insights into analysis of inkjet inks
Continuous learning is the key to success
When you are running a research lab, or trying to complete a project, or troubleshooting a product quality issue, you always need good data and clear results. It is not always easy to know whether you have performed an analysis or interpreted your data correctly. That is where continuous learning comes in. It is always great to take time out of your busy schedule to refresh what you know and maybe learn something that you did not know.
That is exactly what some of our industry partners did. From July 11th to July 14th, Malvern Panalytical joined a team of analytical experts in Cambridge, UK, to present a 4 day hands-on course hosted by IMI Europe. There was a select group of analysis experts covering the analytical methods necessary for the development and manufacture of quality inks for different inkjet processes.
Analysis of inkjet inks
It is all in the detail, or to be more scientific, it is all about the nanoparticle pigments, the polymer binders, the extenders, dispersants, solvents and more. In particular, our team from Malvern Panalytical talked about how to measure pigment particle size and shape using laser diffraction (LD), dynamic light scattering (DLS), how to predict and maintain ink stability with electrophoretic light scattering (ELS) and how to measure polymer properties such as molecular weight and conformation using gel permeation chromatography (GPC/SEC).
John Ddungu described how to use Mastersizer 3000 to identify oversized particles and how to track the progress of pigment milling to achieve an optimum particle size of 200nm and how, with the Hydro Insight, you can also look at the oversized particles’ shapes. Diogo Fernandes discussed measurements of pigments and the options for measuring pigment dispersions at higher concentrations using Zetasizer Advance. He also talked about and how to use the same instrument to measure colloidal stability using zeta potential and how to detect particle agglomeration. Serena Agostini described the roles of polymers in inkjet dispersions and how to use GPC with OMNISEC to help predict ink drop behavior.
Not only did the attendees have workshops on the theory and practice. They also had the opportunity to see the instruments in action and try out some of their own samples.
Sometimes it is just great to take time out of the busy work schedule and think about what you are doing. Continuous learning is a great way to see your product in a new light.
