Identifying microplastic litter with Laser Induced Breakdown Spectroscopy: A first approach

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Sommer et al used LIBS to identify microplastic litter . 111 A Q-switched Nd:YAG laser operating at 532 nm and with a frequency of 10 Hz and energy of 200 mJ was used for the measurements, with detection achieved using a spectrometer equipped with an intensified CCD. Reference pieces of assorted polymers were used to “calibrate” the system.…”

Water Analysis: Emerging Contaminants and Current Issues

“…Laserinduced breakdown spectroscopy (LIBS) was used by Sommer et al in a new method to identify MPs. 233 LIBS produced specific spectral fingerprints that could pinpoint the type of plastic without any sample preparation.…”

“…A new multistep method utilizing polymer–dye binding chemistry, density tests, unique surface morphological traits, and fluorescent staining was reported by Zhu et al Different polymer types could be identified with this method (at a success rate of 67%), which offers an advantage of not requiring expensive spectroscopic instrumentation. Laser-induced breakdown spectroscopy (LIBS) was used by Sommer et al in a new method to identify MPs . LIBS produced specific spectral fingerprints that could pinpoint the type of plastic without any sample preparation.…”

Nile Red staining for the detection of microplastics: a comprehensive study on the emission spectra

“…Recently, other spectroscopic approaches have been explored, including laser-induced breakdown spectroscopy [14] and time-integrated [15,16], as well as time-resolved PL spectroscopy [17]. Timeintegrated PL is inexpensive yet less precise than the other mentioned methods when identifying the polymer class.…”
