Mold & Bacteria Consulting Laboratories (MBL) inc., is now using the new ASTM method D7391-09 for analysis of non-viable air samples. Until recently, there has been no standard method by which to analyze non-viable air samples collected by inertial impaction samplers such as Air-O-Cell, Allergenco-D, micro 5 and other similar samplers.
The American Society for Testing Materials (ASTM) International published the new standard method, D7391-09 entitled “Standard Test Method for Categorization and Quantification of Airborne Fungal Structures in an Inertial Impaction Sample by Optical Microscopy”.
The method outlines two procedures for enumerating fungal structures: one for slit impaction samples such as air-o-cell and allergenco-D and the other for circular impaction samples such as micro 5. Analytical results are presented in fungal structures/sample (fs/sample) and fungal structures/m3 (fs/m3)
