For your current review, all calculations have been completed Using the up-to-date value of sixteen.2 ml/min and modified to the particular temperature and strain situation. We also carried out back-calculations to estimate the sampling uptake rate assuming the active technique to be a legitimate reference. The calculated sampling uptake charge was 19.5 ml/min (median price) that has a CV of 1.4. Nonetheless, this sampling rate dependant on 66 sets of paired samples may not be trustworthy as a consequence of the possibly substantial influence of droplets splashed around the inlet on the passive badges, exactly where these have small sample loadings (e.
