Dr. Lois Weyer has been employed in the chemical industry for over three decades, working primarily in spectroscopy and process analysis, specializing in optical spectroscopy. After working for several years in traditional Near IR, UV and Mid IR, she began developing industrial applications for "new" NIR in 1983. This resulted in installations in at least 20 Hercules plants all over the globe. This then lead to the initiation of a process analytical effort at her company, and resulted in installations of IR, near IR, Raman, UV and other systems at a number of US and international plants. She earned an MS degree in physical chemistry in 1971 and Ph.D. in 1996, studying chemometrics under Steven Brown at the University of Delaware. Lois has worked closely with Tres-Ark for 5 years as an analytical chemist with a practical, problem-solving, multi-tasking approach.


EAS Award for achievements in NIR 1992 Delaware Valley Spectroscopist of the Year Award 1999 American Chemical Society, Chair of Delaware Section in 2001 Has served on many industry panels and presented at a number of conferences
