Industry: food & beverage

Ensuring that water, juice, beer, wine and other beverages, dietary supplements and food ingredients, contain low levels of contaminants and are safe to eat, but include the stated amounts of nutrients, is of primary concern to ensure a healthy life for people.

International recommendations on handling of food and analysis of their constituents have been set by WHO and additional guidelines how to analyse food substances are provided in the Food Chemicals Codex assembled by USP. Many regional authorities, including EFSA and national food government agencies are working with WHO and USP to enforce these recommendations and mitigate food fraud. Diduco has contributed by showing that analysis of anions in drinking water according to the requirements set by EPA method 300.1 which also satisfy the demands by corresponding ISO and ASTM methods, and that these analysis can be performed with a flexible equipment to which a setup for suppressed ion chromatography have been connected.

Pharamaceutical counterions with XAMS suppressor and ASUREX-A200

Generic method for isocratic separation of fifteen common pharmaceutical counterions

Many medicines and dietary supplements are bases that carry a positive charge, and these small molecules are consequently accompanied by negatively charged counterions. Such anionic excipients may influence the properties of the pharmaceutical formulation and can also influence the effect of the active ingredient since different ion pairs can have different dissolution rates or abilities to penetrate cell walls.
