Tony  Thornton received both his B.S. degree in Chemistry (cum laude) and his M.S. degree in Analytical Chemistry from Emory University in Atlanta, in 1980. Tony’s research at Emory involved liquid chromatography, specifically the use of ion-pair chromatography and isocratic separation of catecholamines and metabolites. His work supported early research into potential treatment of Parkinson’s disease between Emory and the Veterans Administration hospital in Atlanta.
Tony has been a key member of the Micromeritics team since 1980, specifically evolving the study of particle sizing using liquid chromatography. Tony was also instrumental in developing the SediGraph, DigiSizer, and Elzone, and has made significant contributions to development of products for particle size, physisorption, chemisorption and pycnometer product lines. Most recently, Tony was the recipient of the ASTM International 2021 Cavanaugh Award. He was recognized for outstanding promulgation of standard test methods for powder characterization and for masterful leadership in international standards development organizations.

Jack G. Saad earned his ACS Certified BS Chem degree in chemistry from the University of Georgia. As an undergraduate, he worked with a variety of tungsten compounds to induce photo-initiated polymerization of cyanoacrylate using specific wavelengths of visible light, an application used in the adhesive industry. He began his career at Micromeritics Instrument Corp. as a particle size analyst for their contract laboratory service where he developed protocols to obtain particle size distributions using various techniques. He spent seven years in the pharmaceutical industry in various formulation roles to include raw materials testing, manufacturing support, research and development, and quality control.He rejoined Micromeritics in 2011 in a technical and scientific support role for various characterization techniques.  He also works on collaborations with other organizations and universities to perform research support leading to publications in peer reviewed journals in various fields as well as participate in industry organizations as a subject matter expert, including the United States Pharmacopeia (USP) and the Accrediting Council for Continuing Education and Training (ACCET).

Areas of analytical expertise include: particle size, zeta potential analysis, density measurements, chromatography
