Description

Traditional methods for evaluating microplastics in water environments are hindered by
complexity, accuracy issues, and inefficiency in processing large volumes of water
within realistic timeframes and costs. This patented approach introduces a novel
measurement technique—multispectral transmission evaluation using specifically
prepared pulsed, coherent emission in the visible spectrum. This emission interacts with
water and single plastic particles (LDPE, HDPE, and PP) of various sizes and forms as
they pass through the active sensor volume. This work presents the theoretical
foundation of the method, and the initial results obtained from laboratory experiments
conducted in 2024.
