Accuracy of starch detections using Rapid-E bioaerosol monitor when comparing to EN16868:2019; (A) timeseries of starch granules concentrations and (B) respective scatter diagram with calculated coefficient of determination. (Rapid-E concentrations were scaled linearly with the scaling factor 4.53 obtained by dividing the sum of hourly starch concentrations recorded with EN16868:2019 by the sum of hourly starch concentrations recorded using Rapid-E bioaerosol monitor from four days when data was used for training the classification model).
