photoionization
foh-toh-eye-uh-nuh-ZAY-shun
Definition
A precise analytical method used to detect volatile organic compounds (VOCs) by exposing gas samples to high-energy ultraviolet light, causing the molecules to become electrically charged for measurement.
Etymology
Derived from the Greek 'phōs' (light) and 'ion' (going), combined with the suffix '-ization' to denote the process of creating ions through light exposure. The term entered scientific usage in the 20th century to describe this specific form of radiation-based molecular excitation.
