4 new Application Notes from Metrohm on anions and cations in beer, organic acids in wine, carbohydrates in coffee, and GOS analysis in novel foods are now available for free download.
Metrohm is pleased to support the food and beverage industry with 4 applications utilising ion chromatography with pulsed amperometric detection (PAD) for the fully automated determination of multiple GOSs (β-galactooligosaccharides) and carbohydrates in novel foods and instant coffee, respectively, key anions and cations in beer, and organic acids in wine.
Foodstuffs are a difficult matrix to analyse as matrices are often solid and many liquids contain particles that pose a challenge to any kind of chromatographic method. At the same time, regulations require the food and beverage industry to comply with numerous norms and standards. Metrohm ion chromatography with automated inline sample preparation (e.g., inline ultrafiltration, inline dialysis, inline matrix elimination) addresses the matrix challenge most effectively.
Moreover, ion chromatography makes it possible to determine multiple similar compounds (e.g., various carbohydrates) with a single analysis in compliance with the latest AOAC standards.
The 4 Application Notes are:
- Quality labels of novel foods – Improvement on AOAC 2001.002: GOS analysis with IC-PAD
- Quality assurance of instant coffee – Free and total carbohydrate determination with IC-PAD according to AOAC 996.04 and ISO 11292
- Anions and cations in beer – Streamlining beverage analysis with ion chromatography
- Assessing wine quality with IC – Organic acid analysis using suppressed conductivity detection
