Metrohm is pleased to support the food and beverage industry with 4 applications utilizing 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 analyze 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 an 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. Metrohm applications exemplifying the efficiency and versatility of ion chromatography with Metrohm Inline Sample Preparation (MISP):
- Quality labels of novel foods – Improvement on AOAC 2001.002: GOS analysis with IC-PAD
- Quality assurance of instant coffee – Free and total carboydrate 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
