FEATURES
Packing Light: Spectroscopy Goes Mobile Dec 7, 2020 — Portable spectroscopic instruments have dramatically expanded their capabilities and detection limits over the past 20 years, while becoming smaller, lighter, and faster. The examples of this today are legion. Portable laser-induced breakdown spectroscopy instruments now enable the critical measurement of carbon in steel, with a detection limit of 100 parts per million. Devices measuring a single cubic inch are available for near-infrared (NIR) and Raman spectroscopy. Portable instruments...
