To better understand environmental and health impact arising from microplastics pollution, reliable methods for their detection and characterization are needed.
Laser Direct Infrared (LDIR 8700) is an emerging, non-destructive spectroscopic imaging method for counting, as well as chemical identification of microplastics down to few micrometers in size. Single particle ICP-MS (spICP-MS) has emerged as a promising technique for the determination of number-based quantification of microplastics with sizes <10 µm. In this lecture, critical considerations and challenges in the development of a spICP-MS method to achieve reliable and accurate particle number concentration quantification will be discussed. Both complementary techniques will be presented in this webinar as well as deeper insights into their potentials for the future.
