Solving Our Plastic Problem: Advances in Microplastics Analysis

Plastic is essential in modern life but is nonbiodegradable primarily, taking up to 400 years to decompose. Production has skyrocketed, leading to widespread microplastic pollution. Agilent is tackling this issue with advanced tools for analyzing microplastics, aiming to better understand and mitigate their environmental and health impacts.

Webinar: Challenges in Microplastics Analysis—From Routine Laboratory Testing to Pushing the Boundary on Particle Sizes

There are many challenges in the fast-developing field of microplastic analysis. In this webinar, we will hear from two speakers addressing quite different challenges, but nonetheless, challenges faced by many. The first speaker, Dr Gbotemi Adediran from the UK Centre for Ecology and Hydrology, will explore the opportunities and challenges in analyzing sub-micron-sized (< 5µm) microplastics analysis by LDIR. In the second presentation, Dr Julia Jaeger from Eurofins Environmental Testing—Australia & New Zealand will explore advancements and challenges related to the application of LDIR for routine microplastic analysis.

LDIR Enables Accurate Microplastic Characterization in Infant Formula

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. In a recent application note, the 8700 LDIR Chemical Imaging System was used to accurately identify and quantify microplastics in infant formula. The study also shows the importance of quality control in microplastics analysis. Read the application note.
