Rheological and Particle Characterization Lab Opens at Covalent Metrology; Dr. Sophia Yan to head this lab and lead Covalent Academy this week
May 8, 2020 — Sunnyvale, CA. — Covalent Metrology is excited to formally announce the hiring of Dr. Sophia Yan to run our newly commissioned Rheological and Particle Characterization lab. As was announced in Dec, 2020, the facility will dually serve another purpose as the Silicon Valley demo lab for our strategic instrument partner, Anton Paar. Covalent Metrology is thrilled to be showcasing their suite of instrumentation for advanced rheological and particle analyses.
We are pleased to announce that this lab is now up and running! Dr. Yan and her team can now provide measurement and characterization of a number of critical materials properties:
- Bulk Rheological Parameters – The best-in-class MCR 302 measures both time and temperature dependence of bulk rheological parameters such as viscosity and shear modulus. Rheological properties such as shear thinning, gelation and aging are critical insights to the performance and stability of many consumer and commercial products.
- Dynamic Light Scattering (DLS) & Zeta Potential for Colloids – The Litesizer™ 500 measures zeta potential of colloidal dispersion in high concentrations up to 70% w/v in aqueous and non-aqueous media. DLS is typically utilized in characterizing the Brownian motion of particles and colloids. It provides useful information for formulation development such as stability and size distribution of dispersed particles and emulsions.
- Dry Powder and Liquid Particle Size Analysis – The versatile PSA 1190LD can disperse, deagglomerate, and analyze the full measurement range of particle size from 40nm to 2.5mm. This laser diffraction instrument covers many applications of ingredient powders, pastes, slurries and dispersions used in pharmaceuticals, cosmetics, food, semiconductor, and biotech.
- Zeta Potential for Solid Surfaces – The state-of-the-art SurPASS™ 3 mesaures zeta potential for active surfaces such as semiconductor wafer and pads, surface adsorption kinetics such as water filtration systems, and pH-dependent isoelectric points. Additionally, thermal management up to 40 deg C will enable temperature-controlled studies which are often required for bio-pharma industries.
This week on Covalent Academy, Dr. Yan will kick off the new lab launch a webinar on the field of particle characterization: what is entails, why it matters, and how it’s done. Her talk will also highlight key considerations for the industrial applications of these techniques, and comment on some practical aspects of instrumentation.
The event, Particle Analysis for Industrial Product Success, will be aired live at 11am PDT on May 14th. Click below to register for this upcoming webinar!
