Abstract

This paper describes the construction of a long-path fourier transform instrument based on a BOMEM MB100 spectrometer, as well as the initial application for VOC monitoring at an automobile painting facility. The instrument gave detection limits of about 100 ug/m³ for a number of aromatic hydrocarbons along a 350 m folded measurement path (single end retroreflector setup, 180 scans, 1 cm^-1 resolution). The instrument also yielded a detection limit of about 10 ug/m³ for butyl acetate which promotes this compound to be used as a tracer for VOC emissions originating from the automobile industry. The paper also includes a description of the spectral analysis applied involving single component classical least square fit and correction for water vapor interference.
