Measurement of deposited particulate mass from a 24 minute ISO smoke exposure using 3R4F cigarettes at airflows 0.5-4.0 L/min [a] and reciprocal airflow (1/ airflow (L/min)) of; 2.0, 1.0, 0.5 and 0.25 respectively [b], with a vacuum of 5 ml/min/well. Results are based on three independent experiments with four QCM readings per experiment. [a] shows an individual value plot of obtained deposited mass values. For airflows of 0.5, 1.0, 2.0 and 4.0 L/min mass values of 5.9 ± 0.36, 3.3 ± 0.28, 1.6 ± 0.23 and 0.6 ± 0.08 μg/cm2 were obtained respectively. [b] shows data presented as a reciprocal of the airflow (1/airflow (L/min)) with a regression fit correlation of R2 = 0.975 with 95% confidence (red dash) and probability (grey dash) intervals.
