Agilent Hi-Plex H is a high-performance ligand-exchange chromatography column that can be used for quantitative analysis of organic acids in red wine, white wine, rosé wine, and dessert wine.

This application note demonstrates the superior separation ability of Agilent Hi-Plex H in the analysis and quantification of the organic acids in wine, by comparison with a column from another manufacturer.

The Application Note introduces the experimental method used for analyzing the organic acid content of various dairy products using the Agilent Hi-Plex H column.

Agilent Technologies, Inc. Rapid Profiling of Saccharides Using HPLC with ELSD for Improved Precision Application Note

This application note describes the USP analysis of seven sugar alcohols on an Agilent Hi-Plex Ca column, including sample preparation, chromatographic conditions, and results.

This application note describes the HPLC analysis of byproducts in fermentation liquids using an Agilent Hi-Plex H column.

This application note describes the analysis of organic acids in silage using high-performance liquid chromatography (HPLC). The concentration of lactic acid, acetic acid, and butyric acid in silage can be determined by adding water and filtering the sample. This method is applicable for the analysis of grass, whole plant, and corn silage.

This application note demonstrates how an Agilent Hi-Plex H column can be used to separate aliphatic alcohols.

This document introduces the application of Agilent Hi-Plex columns, which are mainly used for the separation of carbohydrates, alcohols, and organic acids. These columns use ion-exchange ligand-exchange columns, suitable for the analysis of compounds such as simple sugars, alcohols, oligosaccharides, and organic acids in foodstuffs. The columns use isocratic conditions with water as the eluent and temperature as the main variable for control of resolution. When samples contain organic acids, especially in the presence of neutral mono- and disaccharides, Agilent Hi-Plex H is the preferred option. The column is run using water as the eluent for the analysis of sugars and organic acids or, more commonly, dilute acid for separation.

This application note introduces a method for detecting artificial sweeteners in wastewater, which uses solid-phase extraction (SPE) to effectively extract sweeteners from water for LC/MS detection.

This application note describes the method for detection of nanogram levels of explosive constituents in seawater samples, after explosion of ordnance devices.
