Accurate Microplastic Characterization in Infant Formula Using the Agilent 8700 Laser Direct Infrared LDIR Chemical Imaging System
Author(s)Agilent Technologies, Inc.
Reports of the omnipresence of microplastics have mainly focused on their presence in the environment, but there is a growing interest in investigating the health impacts of microplastics. Many people would assume that infants' exposure to microplastics would be limited. However, infant formula was found to be a possible exposure pathway. Extracting and isolating microplastics from infant formula can be difficult due to the range of formulations, ingredients, and components, such as fats, proteins, minerals, vitamins, and sugars. This application note demonstrates the importance of quality control in microplastics analysis. The study also shows how the Agilent 8700 Laser Direct Infrared (LDIR) Chemical Imaging System can accurately identify and quantify microplastics in infant formula.
