Abstract
Smoke emission measurement by conventional filtering techniques is inaccurate for low levels of smoke (below ~2 mg/m3). Here photothermal deflection spectroscopy (PDS) is used to measure low levels of smoke emitted from a diffusion flame. In the PDS smoke instrument, an argon-ion laser heats the smoke sample and the deflection of a He–Ne laser probe beam is detected by a position sensor. The beam deflection is directly related to the smoke density. Using PDS, smoke emissions from an acetylene flame are detected at levels as low as 50 μg/m3 (5 × 10−6 cm−1 light absorption).
