OPERATOR AIR: DETERMINATION OF THE CONCENTRATION OF ASBESTOS FIBERS
Analysis determining the concentration of asbestos fibers in the air
À propos de cette analyse
ANALYSIS METHODS
Detection and counting of asbestos fibers and identification of the fibers’ type in the sampling of operator air, by observation with the transmission electron microscope (TEM)
TECHNIQUES AND MATERIALS EMPLOYED
Identification through a TEM analysis of the morphology of the fibers and additional analysis using the electronic diffraction methods and energy-dispersive X-ray spectroscopy
NATURE OF THE RESULTS
Results are quantitative: the number of asbestos fibers observed and the analytical sensibility measured depending on the target and the volume of the sampling.
ESTIMATED TIME
Day 1, day 3 or day 5
SAMPLING
Sampling cassettes labelled and packed in waterproof zip lock bags, with the sampling sheet ; you can also gather the same sampling filters’ position.
NORM and REFERENCE
NF X 43-050 ; LAB REF 28
