QuoData presents the results of the current GSR Proficiency Test and the results of a collaborative study on the Forensic Determination of Shooting Distances

The 20th annual meeting of the ENFSI expert working group Firearms/GSR (Gunshot residues) takes place in Riga, Latvia on 10-13 September.QuoData being a longtime partner of the Bundeskriminalamt (BKA) will provide the latest results of the GSR proficiency test. Furthermore, the collaborative study on the Forensic Determination of Shooting Distances funded by the EU and performed in 2012, was analyzed by QuoData with assistance of BKA experts. The results are presented now at the meeting.

Both studies have been evaluated with PROLab which is a QuoData-specific software to assess the performance of laboratories in interlaboratory tests. PROLab is recognized as reference software for these kinds of studies in Europe.

In close cooperation with the ENFSI, QuoData realizes independently the organization and analysis of the annual international GSR quality scheme since 2009. Within this proficiency test all participants determine gunshot residues by means of scanning electron microscopy. The test samples can also continue to be used for internal quality assurance by the laboratories as QuoData provides an automatic web service. 

Besides ENFSI and QuoData are cooperating in terms of planning an international proficiency test on the forensic determination of shooting distances. In order to assure the quality and to optimize the method for the shooting distance determination QuoData contributes its mathematical-statistical expertise and is responsible for statistical concepts and analysis.
