Evaluation of Radiello diffusive sampler indicated for thermal desorption for measuring VOCs in ambient air.

Abstract

- One of the key aspects regarding air monitoring is to determine the suitability of the methodology chosen. -The comparison between validated active air multi-sorbent tubes and Radiello diffusive samplers show no significant differences between the two methodologies for several compounds studied. -For the Radiello passive sampler, relevant differences have not been observed between the sum of two shorter sampling periods (4 days + 3 days) and a longer sampling period (7 days). -The Radiello diffusive sampler provides satisfactory quantitative measurements and is suitable for the determination of several VOCs in ambient air. -Radiello passive sampler coupled with ATD-GC/MS is a simple to use, sensible and cheap method to assess ambient air concentrations of VOCs. -More research has to be done to enhance the results obtained in this study.
