A 10 slpm coiled denuder has been designed and experimentally characterized. Its geometrical parameters and operating characteristics are summarized in Table II. The gas collection efficiency for SO2 exceeds 99% and thus is comparable with annular denuder efficiencies. Experiment has shown that the particle loss is small for neutral particles in the size range 0.015-2.5 micro m. Particle loss measurements also indicate that the unit can operate equally well in any orientation. The short axial length (6 cm) of the coiled denuder has the advantage that a denuder train of multiple units in series will have a total length that is substantially less than a corresponding train of annular denuders.
