    摘要: This study focuses on a novel, multipass, acoustically open photoacoustic detector designed for fast-response high-sensitivity detection of formaldehyde adsorption by bamboo charcoal in an ambient atmosphere. The detection range, estimated from formaldehyde measurements at a wavenumber of around 2805 cm−1, is 0–2.0 parts per million by volume. In this work, photoacoustic (PA) detection with various bamboo charcoals was analyzed at our laboratory for the detection of a photoacoustic signal using a pulsed laser system and the comparative performances of the charcoals were studied. The PA system is applicable to pollution monitoring and detection of hazardous gases in an indoor environment.
