Biomass burning is a major source of particulate matter present in atmospheric aerosol. Anhydrosugars, sugar alcohols, monosaccharides, and disaccharides are among the major classes of water-soluble organic compounds (WSOC) in atmospheric aerosols. Saccharides have been proposed as markers to evaluate the contribution of these sources to atmospheric aerosols. Here, we developed an improved single column HPAE-PAD method to determine anhydrosugars, simple sugars, and sugar alcohols present in atmospheric aerosol samples using CarboPac PA300 column.
This application note describes a convenient, fast, and sensitive method that uses a Thermo Scientific™ Dionex™ CarboPac™ PA300 column and electrolytic eluent generation. The Dionex CarboPac PA300-4μm column is packed with a new 4 μm particle size supermacroporous resin to achieve high efficiency and high-resolution separations. Using this column, a 16.8 min method that resolved six analytes, including glycol and other carbohydrates, was designed. Results for method linearity, robustness, and accuracy for glycol and carbohydrate quantification in OTC samples are discussed here.
To demonstrate that the Norma Oficial Mexicana (Official Mexican Standard) method for agave syrup carbohydrate analysis can be executed with a Thermo Scientific™ Dionex™ CarboPac™ PA200-1 mm column using a KOH/KMSA eluent produced electrolytically using dual eluent generation cartridge (Dual EGC) mode
In this application note, we describe a new method involving eluent generation and high pressure ion chromatography with 4 μm particle size resin for sorbitol determination in fruits and beverages. This methodology provides faster results and improves reliability with perfect and automatic control of eluent concentration.
This application demonstrates that the Norma Oficial Mexicana (Official Mexican Standard) method for agave syrup carbohydrate analysis can be executed with a Thermo Scientific™ Dionex™ CarboPac™ PA1-1mm column using KOH/KMSA eluent produced electrolytically using Dual Eluent Generation Cartridge (Dual EGC) mode.
