[Hydrophilic interaction chromatography and its recent applications in environmental analysis]

Environmental monitoring requires reliable methods for separating polar compounds. Traditional reversed-phase liquid chromatography (RPLC) faces limitations with highly polar analytes. Prior research has shown that RPLC struggles with retention of such compounds due to poor solubility in organic mobile phases. This gap motivated exploration of alternative separation methods. Hydrophilic interaction chromatography (HILIC) emerged as a promising approach. It offers better retention of polar substances by using a water-rich mobile phase. No prior work had resolved the full potential of HILIC in environmental contexts. That uncertainty drove recent studies to evaluate HILIC's suitability for environmental pollutants.

This review aims to clarify HILIC's role in environmental analysis. The specific problem is the growing need for effective separation of polar pollutants. The motivation stems from limitations in current chromatographic methods. The authors sought to summarize HILIC's development and retention mechanisms. They also aimed to compare HILIC with RPLC for environmental pollutants. The goal was to assess advantages and disadvantages of each method. By doing so, the study sought to guide future environmental analysis. The review also aimed to highlight recent trends in HILIC application.

The authors conducted a literature review of HILIC applications in environmental analysis. They analyzed HILIC's development history and retention mechanisms. The study compared HILIC with RPLC in terms of separation efficiency. They evaluated HILIC's advantages, such as low mobile phase viscosity. The authors also assessed column permeability and sensitivity with mass spectrometry. They reviewed case studies where HILIC was used for polar pollutants. The review included discussions on HILIC's limitations in environmental settings. The synthesis of findings focused on environmental analysis trends.

HILIC showed superior retention of polar compounds compared to RPLC. The method's low mobile phase viscosity improves system performance. Column permeability was found to be better in HILIC setups. Coupling HILIC with mass spectrometry increased detection sensitivity. The study noted HILIC's lower back pressure as a key advantage. Applications in environmental analysis included pesticide and pharmaceutical detection. HILIC's ability to separate strongly polar pollutants was confirmed. Recent trends suggest growing adoption of HILIC in environmental studies.

The authors propose that HILIC is a valuable supplement to RPLC in environmental analysis. They suggest that HILIC's advantages include better separation of polar compounds. The review highlights HILIC's compatibility with mass spectrometry detection. The authors note that HILIC reduces system back pressure compared to RPLC. They propose that HILIC is particularly useful for strongly polar pollutants. The study suggests that HILIC may become more widely adopted in environmental labs. The authors suggest that HILIC's retention mechanism is well-suited for polar analytes. They conclude that HILIC has clear advantages for environmental separation tasks.
