應用
- Development of HPLC-ELSD method for determination of maltodextrin in raw milk: Demonstrates the utility of the SUPELCOSIL LC-NH2 HPLC Column in the food industry, specifically in dairy product analysis. This study highlights the column′s effectiveness in separating and quantifying maltodextrin, a common food additive, using high-performance liquid chromatography (HPLC) with evaporative light scattering detection (ELSD). The method developed is vital for ensuring product quality and adherence to food safety standards (Moraes FS et al., 2017).

An analytical method was developed and validated for the determination of maltodextrin in raw milk, using high-performance liquid chromatography with evaporative light scattering detection. Maltodextrin content was evaluated in adulterated raw milk using a Supelcosil LC-NH2 (25cm×4.6mm) column and isocratic
