Identifying a suitable mounting medium for use in forensic fibre examination

As the result of a previous study many laboratories have used XAM neutral medium-improved white mounting medium in textile fibre examination for more than 20 years. Due to European Directive 98/79/EC, XAM is no longer available and an alternative needed to be found. A list of desirable properties was formulated and a number of mounting media were tested against this. Entellan New was identified as the best mounting medium, and performed similarly to XAM in all aspects.
