Applications of Ion Chromatography Instrument in the Food Industry
Ion chromatography (IC) is a powerful analytical technique widely used across various industries for the separation, identification, and quantification of ionic species. Below is an overview of its applications in different industries along with typical system configurations tailored to specific needs:
Additives: Determine the content of sweeteners (saccharin sodium, acesulfame, etc.), preservatives (benzoic acid, sorbic acid, etc.), antioxidants (sulfites, etc.) in food to ensure food safety.
Nutritional Analysis: Determine the content of mineral elements (Na, K, Ca, Mg, Fe, Zn, etc.) in food to evaluate the nutritional value of food.
Pesticide Residue Detection: Detect pesticide residues such as organophosphorus and organochlorine in food to ensure food safety.
Contaminant Detection: Analysis of trace-level contaminants such as perchlorate, nitrite, and bromate in drinking water and food.
Quality Assurance: Monitoring of organic acids (e.g., acetic, citric) and preservatives in beverages.
