Journal ArticleDOI
Effect of impact stress on microbial recovery on an agar surface.
TL;DR: Comparison of results from the agar slide and Andersen impactors at the same sampling velocity showed that recovery and injury due to collection depends not only on the magnitude of the impaction velocity but also on the degree to which the microorganisms may be embedded in the collection medium.
Journal ArticleDOI
Comparison of methods for detection and enumeration of airborne microorganisms collected by liquid impingement.
S Terzieva,Jean Donnelly,V. Ulevicius,Sergey A. Grinshpun,Klaus Willeke,G N Stelma,K P Brenner +6 more
TL;DR: This study compares four methods for the detection and enumeration of aerosolized bacteria collected in an AGI-30 impinger to determine the changes in viable bacterial concentration during the impingement process.
Journal ArticleDOI
Effect of relative humidity on the aerodynamic diameter and respiratory deposition of fungal spores
TL;DR: In this article, the authors investigated the change in aerodynamic diameter of five different fungal species as a function of relative humidity and found that most fungal spores are only slightly hygroscopic.
Journal ArticleDOI
Effect of Impaction, Bounce and Reaerosolization on the Collection Efficiency of Impingers

TL;DR: In this paper, the collection efficiency of liquid impingers was studied experimentally as a function of the sampling flow rate with test particles in the bacterial size range, and three impingers were tested: two All-Glass Impingers (AGI-4 and AGI-30) and a newly developed slot impinger.
Journal ArticleDOI
Effect of Sampling Time on the Collection Efficiency of All-Glass Impingers
TL;DR: In this article, the inner diameter of the impingement nozzle was found to be the most critical dimension affecting the collection efficiency of all-glass impingers and significant variations were found in the performance of individual impingers due to the variations in the critical dimensions of impingers tested.
