Using the Right Tool for the Job: A Selectivity-Driven View of Alternative Bonded Phases and HILIC
Conventional C18 reversed-phase columns remain the default choice for many HPLC separations, yet their widespread use can obscure opportunities for improved performance through alternative selectivity. This work examines retention mechanisms associated with nontraditional stationary phases, with particular emphasis on embedded polar group and fluorinated reversed-phase materials. In addition, the use of hydrophilic interaction liquid chromatography (HILIC) for alternative selectivity is explored. By dissecting the molecular interactions governing retention and selectivity, this contribution highlights how changes in stationary-phase chemistry can produce substantial gains in resolution, robustness, and method simplicity.
Nomination for Annual Uwe D. Neue Award in Separation Science at HPLC 2026
About the Award
The Uwe D. Neue Award was created to recognize scientists that have made and continue to make significant contributions to the field of separation science, in honor of the legacy of Dr. Uwe D. Neue, late scientist and Waters® Corporate Fellow. The award will be given at the at the 55th International Symposium on High-Performance-Liquid-Phase Separations and Related Techniques (HPLC 2026) held from June 6-11, 2026 in Indianapolis, Indiana, USA. The award is sponsored by Waters Corporation.
Eligibility Criteria
The UDN award will honor a distinguished industrial scientist, 15-20 years or more after receiving his or her degree, who has made a significant contribution to the field of separation science. In addition, the awardee should be an industrial scientist, and one who was instrumental in the embodiment of technology in commercial products.
Nominations
The deadline for completing and submitting the nomination information packet is December 31, 2025. The nomination packet will include a CV with nominating letter by the original nominator and a supporting document by a second person. Both letters should describe an individual's impact on separation science based on presentations, publications, patent records, prior honors, and contribution to innovative products as well as impact on others who he/she has managed or trained. The packets will be valid for three consecutive years. The packet should be submitted to Martin_Gilar@waters.com.
Selection Process
Nominations will be considered by a group consisting of selected members of the Permanent HPLC Symposium Committee, and industrial researchers.
Awardees
The award recipient will receive a commemorative plaque, a $7,500 check and travel support. He/she will have an opportunity to present a research lecture at the following HPLC Symposium. The 2026 award will be given at the 55th International Symposium on High-Performance-Liquid-Phase Separations and Related Techniques (HPLC 2025) held from June 6-11, 2026 in Indianapolis, Indiana, USA.
