“…Krimen agertokian tiro-aztarnak osatzen dituzten konposatuen detekzioak eta identifikazioak su-armen erabileraren ebidentzia fidagarria eskaintzen du. Hala ere, auzitegi-analisiaren ikuspuntutik, su-arma bat ustez kliskatu duen pertsona baten identifikazioa argitzeko, ezinbestekoa da bere gorputzean aurki daitezkeen tiro-aztarnak ziurtasun osoz identifikatzea [73].…”

Laburpena: 80ko hamarkadaz geroztik, laser bidezko ablazioa eta akoplamendu induktibozko plasma-masa espektrometria (LA-ICPMS) konbinatzen dituen teknika analitikoa sakonki ikertu eta garatu da, eta, gaur egun, lagin solidoen analisi elemental zein isotopiko zuzena egiteko erreferentziazko teknika bilakatu da. Ezaugarri bereizgarrienak hauexek dira: erabilpen erraza, analisi-denbora laburra, laginari eragindako kalte urriak, sentsibilitate handia eta elementu nagusi zein minoritarioen eta ratio isotopikoen aldibereko neurketa ahalbidetzen duen tarte dinamiko zabala. Lan honetan, LA-ICPMS teknikaren oinarriak eta konfigurazio orokorra azaldu eta femtosegundo/ nanosegundo laser bidezko ablazioaren erabileraren arteko desberdintasun nagusiak nabarmentzen dira. Azkenik, teknika honen egungo egoeraz jabetzeko, jatorri askotariko laginen analisi elementala laburbildu eta berrikusten da biologian eta ingurumenean, osasunean, geokimikan zein auzitegi zientzien alorretan.Hitz gakoak: Laser bidezko ablazioa (LA), akoplamendu induktibozko plasma-masa espektrometria (ICPMS), femtosegundo, nanosegundo, lagin solidoen analisi zuzena. Abstract:Since the early 80s, laser-ablation inductively-coupled-plasma mass spectrometry (LA-ICPMS) has been widely explored and nowadays is considered to be one of the most versatile analytical techniques for the direct trace elemental and isotopic analyses of solid samples. The most remarkable features are ease of use, fast sample throughput, limited sample damages, high sensitivity and wide dynamic range which allows the simultaneous acquisition of major and trace elements, as well as the meas-EKAIA 31.indd 45 EKAIA 31.indd 45

“…Several of the techniques highlighted in table 4 have been further developed since the publications of the mentioned reviews [2,3,7,56]. Although developments are not limited to a specific type of technique, significant progress has been made with a number of methods including IMS, HPLC-MS and CE.…”

“…Consequently, these tests are used less frequently nowadays [2,3]. FTIR has been used as a probe for the analysis of the distribution of OGSR in and around bullet entrance holes and to estimate firing distances [56]. It has also been used as a confirmatory technique after HPLC-UV analysis, to enable a positive identification of nitrocellulose [3,60].…”

(J.W. Birkett). Highlights A list of 136 compounds associated with organic gunshot residue (OGSR) is presented  Recent developments in methods for the extraction and detection of OGSR are highlighted  Analytical techniques aiming to provide a full chemical profile are discussed  It is concluded that the optimal methodology for any OGSR sample should be based on a 'case-by-case' approach 2 Abstract A comprehensive review of the literature concerning all aspects of sampling and analytical techniques used for the determination of organic gunshot residue (OGSR) compounds is presented. Currently, 136 compounds associated with OGSR have been identified in the literature. Despite this area gaining increasing attention and recognition in recent years, there is still an absence of a set combination of sample collection, extraction and analysis methods that are universally optimal for the treatment of any given OGSR sample. Moreover, there are no generally accepted guidelines for selecting the compounds of interest that will inform sampling and analysis protocols. Recent developments in both extraction and analytical methods employed for their detection are highlighted. The main advantages and disadvantages of the sampling and analysis methods are critically discussed.

“…Gunshot residue (GSR) consisted of the characteristic burnt, partially burnt, and unburnt combustion products in combination with the constituents from primers, bullet, cartridge case, and/or firearm itself . Due to the frequent occurrence of crime involving firearms, GSR analysis and examination have gained importance in criminal investigation . Generally, these residues can be traced on surfaces in contact or apprehended with the components of ammunition, including the hand of a shooter, the firearm, the target , and also the cartridge cases .…”

Gunshot residues, produced after shooting activity, have acquired their importance in analysis due to the notoriety of firearms-related crimes. In this study, solid-phase microextraction was performed to extract the headspace composition of spent cartridges using 85-μm polyacrylate fiber at 66°C for 21 min. Organic compounds, that is, naphthalene, 2,6-dinitrotoluene, 2,4-dinitrotoluene, diphenylamine, and dibutyl phthalate were detected and analyzed by gas chromatography-flame ionization detection technique. Evaluation of chromatograms for diphenylamine, dibutyl phthalate, and naphthalene indicates the period after a gunshot was discharged, whether it was 1 days, 2-4 days, <5 days, 10 days, 20 days, or more than 30 days ago. This study revealed the potential effects of environmental factors such as occasional wind blow and direct sunlight on the estimation of time after spent cartridges were discharged. In conclusion, we proposed reliable alternative in analyzing the headspace composition of spent cartridges in a simulated crime scene.
