Asbestos releases fibres into the air if it becomes damaged or disturbed and asbestos fibre inhalation is associated with lung diseases, i.e., asbestosis, mesothelioma and lung cancer.<\/p>\n<p>Airborne asbestos fibres are sampled by drawing a measured volume of air through a membrane filter. This is then mounted onto a microscope slide and rendered transparent with solvents, generally acetone\/glycerol triacetate. Fibres on a measured area of filter are counted using phase contrast microscopy (PCM) and the number concentration of fibres in the air is calculated.<\/p>\n<p>Casella offers specific sampling accessories for the analysis of asbestos fibres; An open faced filter holder fitted with an electrically conducting cylindrical cowl is required along with MCE filters with a printed grid. MCE filters (a mixture of cellulose acetate and cellulose nitrate) are recommended for asbestos sampling as they are readily rendered transparent for fibre counting. Pre-loaded asbestos cassettes are also available in pore sizes of 0.8\u00b5m and 0.45\u00b5m for ease of use.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/airsamplingsolutions.com\/wp-content\/uploads\/2014\/05\/Anthophyllite_asbestos_SEM.jpg\" alt=\"\" width=\"350\" \/>\n<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Asbestos is a group of naturally occurring fibrous silicate minerals which have been used widely in construction and industry because of its flexibility, strength, chemical resistance, insulation properties and non-combustibility.
