Common methods for sampling airborne microorganisms employ either collection onto a filter, impaction onto an agar surface, or impingement into a liquid. In reporting the data obtained with any of the commercially available instruments, the sampling device needs to be specified, as each device covers a different particle size range and has different physical and biological collection efficiencies. Therefore, each device needs to be calibrated for the airborne microorganisms it collects. This study was undertaken to find a suitable method for dynamic size spectrometry of airborne microorganisms, which can be applied for calibrating bioaerosol samplers.
