MPL Laboratories is NATA accredited to identify asbestos fibres in bulk samples using Polarised Light Microscopy (PLM). Three types of asbestos commonly used in manufacturing are chrysotile, amosite and crocidilite. These can be detected by PLM. Fibres which cannot be identified by PLM can be confirmed by Scanning Electron Microscopy (SEM). MPL Laboratories subcontract this work.
