Selecting an Excitation Wavelength for Raman Spectroscopy

Igor Lednev, Rachel Martin, and Jeanne Pemberton were all honored at the 2024 Eastern Analytical Symposium for their work across in variety of spectroscopic techniques and applications.

Microplastics (MPs) and nanoplastics (NPs) are emerging contaminants requiring robust analytical techniques for identification and quantification in diverse environmental and biological matrices. This review highlights various spectroscopy methods, such as Raman, FT-IR, NIR, ICP-MS, Fluorescence, X-ray, and NMR detailing their methodologies, sample handling, and applications for characterizing MPs and NPs.

Laser-induced breakdown spectroscopy (LIBS) is being used frequently in space exploration missions. In this article, we review how LIBS is being used to increase our knowledge of the Moon and certain asteroids.

Laser-induced breakdown spectroscopy (LIBS) is being used to propel many space exploration missions forward. In this two-part article, we recap a recent study that explores the role LIBS is playing in space exploration.
