Rapid Screening of 501 Emerging Contaminants in Water Using Polarity-Extended Liquid Chromatography-Mass Spectrometry

User Benefits

- Polarity-Extended Liquid Chromatography combines hydrophilic interaction chromatography and reversed-phase chromatography to achieve simultaneous analysis of polar and weakly polar compounds. - This method can detect 501 emerging contaminants, offering a broad scope in terms of both quantity and variety. - The water sample is concentrated using freeze-drying method, effectively recovering both polar and non-polar compounds are recovered well.

Introduction

In recent years, water pollution has become increasingly serious, and the problem of emerging pollutants in water has attracted much attention. Traditional analytical methods for emerging pollutants mainly focus on 1-2 categories of emerging pollutants and pay less attention to strongly polar pollutants. The Polarity-Extended Liquid Chromatography, through patented technologies such as polarity splitting, online dilution, and dual gradients, combines a Hilic column (first dimension) and a C18 column (second dimension), which can broaden the polarity analysis range of compounds and achieve simultaneous analysis of polar and weakly polar compounds. In this paper, a method for rapid screening of 501 emerging pollutants was established by using Shimadzu's Polarity-Extended Liquid Chromatography-Mass Spectrometry System. This method solves the problem of simultaneous analysis of strong and weak polar pollutants.
