Titel
Absorption spectroscopy of CO2 at 4.3 m utilizing an off-beam QEPAS Spectrophone and an IR-LED
Abstract
An IR-LED at 4.3 m and an off-beam QEPAS spectrophone as optical detector are utilized for absorption spectroscopy. With an absorption path of 5 cm a detection limit of 150 ppm is achieved for carbon dioxide.
