Bonnie Alden joined Waters Corporation in 1982 to work with Dr. Patrick McDonald to develop new Sep-Pak Cartridge SPE devices. During her career, she has been a member of teams that brought transformative chromatographic columns to market. These include Symmetry Columns which set the industry standard in reproducibility, 1st hybrid chromatographic packing of XTerra Columns, 2nd generation Ethylene Bridged Hybrid (BEH) and Charged Surface Hybrid (CSH) technologies, as well as the recent development of modern, mixed-mode stationary phases for challenging analyses, such as the retention and separation of polar acids. More than 35 years later, she is still an enthusiastic student of liquid chromatography and separation science. Bonnie is currently a principal scientist in the Small Molecule Portfolio Team where her research interests have focused on developing products to address the needs of scientists in the extensive field of small molecule drug development.

Kenneth Berthelette earned his Bachelor's of Science degree in Professional Chemistry from Bridgewater State University, Bridgewater Massachusetts, in 2010. He has been with Waters Corporation since March 2012 and has worked on several product launches including CORTECS Columns, UPC2 Torus and Trefoil columns, and the Atlantis Premier BEH Z-HILIC Column. He changed job functions in 2021 and now supports Chemistry Aftermarket initiatives. His focus on applications and customer education has led to several seminars and webinars on topics including method development, method modernization and transfer, HILIC separation techniques, and LC system troubleshooting.
