Polaris Columns | Normal Phase SFC | HPLC

Features

Polaris phase chemistries are designed for separation in normal phase and SFC modes
The combination of high carbon load, ultrapure silica, and silanol shielding provides superior peak shape and retention with highly polar samples
Polaris columns include chemistries that meet USP L3, USP L8, and USP L10.

How It Works

Customer Testimonials

Dr. Stefan Bieber

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.

Dr. Li Lin

Director of Analysis, Bellen Chemistry Co., Ltd.

KB005945: Agilent Polaris Column Specifications and Options

PFAS Analysis in Milk, Infant Formula, and Related Ingredients Using HPLC

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).
