Ion exclusion columns analyze sugars, carbohydrates, and organic acids.
Ion Exclusion/Ligand Exchange Columns
A series of tools to help you navigate to the best HPLC column choice for your application.
Scale between analytical and prep methods; calculate column capacity, # of injections, run time & mobile phase use.
The InfinityLab Poroshell 120 family has grown to include 3 particle sizes and 19 chemistries, so you can efficiently separate the widest variety of compounds.
Is your purification lab sacrificing speed to find confident answers to research questions?
The Agilent ZORBAX family offers all advantages of totally porous particle columns such as increased retention, loadability and resistance to sample solvents.
Managing Director, AFIN-TS GmbH
Our SFC method development strategy always includes stationary phases of Agilent Technologies, Inc. We strongly appreciate the robustness of polar ZORBAX and Poroshell phases, such as ZORBAX Rx-SIL and Poroshell 120 HILIC. They exhibit good selectivity and high separation performance, which is key for successful and efficient method development in SFC. The broad spectrum of available column dimensions has great advantage for the optimization of separations and allows us to adjust the column dimension to obtain the most efficient separations.View More

Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic chemicals that have been applied in industrial, commercial, and domestic products since the 1950s. Because of their toxicity, persistence, and bioaccumulation potential, PFAS have become global environmental pollutants. Besides the environment, the food chain represents another source of exposure, and the risk related to the presence of PFAS in foods has become of increased interest. Whole milk, infant formula, and ingredients used in infant formula production represent important foodstuffs that require sensitive methods with reporting limits at low parts per billion levels or lower for multiple PFAS. This article summarizes optimization experiments and validation of a complete workflow, including sample preparation and a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for determination of sixteen priority PFAS analytes listed by the U.S. Food and Drug Administration (FDA).
