Abstract

Canine training aids were prepared from filter papers produced with TATP in a gaseous state and with TATP in solution in methanol. High Pressure Liquid Chromatography equipped with a MS/MS detector was used to quantify the amount of TATP present on these training aids. The amount of TATP present on the filter papers prepared from TATP in a gaseous state decreased significantly in 1 h. The canine aids prepared from TATP in solution were more stable, 88% of the initial amount of TATP (99.6 ± 6.0 µg) was still present on the filter papers stored in open air during 10 days. When filter papers prepared by this method were stored in airtight bags, no influence of the storing time on the amount of detected TATP was observed. A one-day testing was performed with 8 dogs. These dogs detected all the types of training aid. Some training aids were prepared 30 days before testing.

犬类训练辅助工具的准备、特性和首次测试

用气态TATP和甲醇溶液TATP生产的滤纸制备犬类训练辅助材料。采用配备MS/MS检测器的高压液相色谱法定量这些训练辅助物上的TATP含量。由气态TATP制备的滤纸上的TATP含量在1 h内显著下降。由溶液TATP制备的犬用助剂更稳定，露天保存10 d后，滤纸上的TATP含量仍为初始含量的88%(99.6±6.0µg)。用该方法制备的滤纸在密闭袋中保存时，没有观察到保存时间对检测到的TATP量的影响。用8只狗进行了为期一天的测试。这些狗发现了所有类型的训练辅助。在测试前30天准备了一些训练辅助材料。

期刊介绍： Forensic Chemistry publishes high quality manuscripts focusing on the theory, research and application of any chemical science to forensic analysis. The scope of the journal includes fundamental advancements that result in a better understanding of the evidentiary significance derived from the physical and chemical analysis of materials. The scope of Forensic Chemistry will also include the application and or development of any molecular and atomic spectrochemical technique, electrochemical techniques, sensors, surface characterization techniques, mass spectrometry, nuclear magnetic resonance, chemometrics and statistics, and separation sciences (e.g. chromatography) that provide insight into the forensic analysis of materials. Evidential topics of interest to the journal include, but are not limited to, fingerprint analysis, drug analysis, ignitable liquid residue analysis, explosives detection and analysis, the characterization and comparison of trace evidence (glass, fibers, paints and polymers, tapes, soils and other materials), ink and paper analysis, gunshot residue analysis, synthetic pathways for drugs, toxicology and the analysis and chemistry associated with the components of fingermarks. The journal is particularly interested in receiving manuscripts that report advances in the forensic interpretation of chemical evidence. Technology Readiness Level: When submitting an article to Forensic Chemistry, all authors will be asked to self-assign a Technology Readiness Level (TRL) to their article. The purpose of the TRL system is to help readers understand the level of maturity of an idea or method, to help track the evolution of readiness of a given technique or method, and to help filter published articles by the expected ease of implementation in an operation setting within a crime lab.
