ABSTRACT:
In response to an identified gap in the forensic document examination discipline, a project to validate the use of IRMS for the comparison of document papers has been undertaken. Initially focused on carbon isotopes, the research included a background study of 80gsm office papers, an examination of the homogeneity to define the ‘source’ level for this material, and an examination of the impact of office-type printing, fingerprint and DNA examinations on papers prior to isotopic abundance measurement. With the project now moving into the use of oxygen isotopes, preliminary findings will be shared, including a discrimination factor for papers where two isotopes are measured. Key results from the carbon studies will be discussed which will include new work conducted to compare the isotopic discrimination value against traditional document examination techniques.
