Tunable Diode Laser Absorption Spectrometer for Detection of Hydrogen Fluoride Gas at Ambient Pressure

Not Accessible

Your library or personal account may give you access

Abstract

We present a tunable diode laser absorption spectrometer (TDLAS) sensor for hydrogen fluoride (HF) detection at ambient pressure operating around the fundamental R(1) transition at 2.476 µm. We achieve 38 ppt sensitivity for 1-s integration time.
