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.
