On the use of IRMS in forensic science: Proposals for a methodological approach

First systematic chemical profiling of cocaine police seizures in Finland in the framework of an intelligence-led approach

“…In this research, the implementation of a chemical profiling methodology at NBI was specifically studied. Such approach requires a thorough reflection about the level of source the laboratory would like or could address [12][13][14]. In the chemical profiling framework, the notion of source is not that trivial and could have various definitions.…”

Precise carbon isotopic ratio analyses of micro amounts of carbonate and non‐carbonate in basalt using continuous‐flow isotope ratio mass spectrometry

“…Repeated measurements reduce the chance of accidental error, so that the deviation of the fitting line is not caused by the large deviation of single datum. Gentile et al considered that the frequency of standards analyzed is governed by the required precision, and that the number of standards and their position can influence the results.…”

Forensic Mass Spectrometry

“…Various physical, chemical, and biological fractionation processes cause localized fractionation of different isotopes and the analysis of the resulting isotopes provenance of different materials. Several reviews have discussed forensic applications of IRMS (105)(106)(107)(108), and Meier-Augenstein (109) provided even more comprehensive coverage in his recent book Stable Isotope Forensics. In forensic applications, isotope ratio analysis provides information about the natural or synthetic origins of scheduled drugs (110)(111)(112)(113)(114)(115)(116)(117)(118)(119)(120), organic and inorganic explosives (76,121,122), petroleum hydrocarbons (such as in ignitable liquids) (65,66,(123)(124)(125)(126), and various other forensic materials (such as fibers, matches, and paint chips) (127)(128)(129)(130)(131).…”
