Laser ablation is becoming a dominant technology for direct solid sampling in analytical chemistry. Laser ablation refers to the process in which an intense burst of energy delivered by a short laser pulse is used to sample (remove a portion of) a material. The advantages of laser ablation chemical analysis include direct characterization of solids, no chemical procedures for dissolution, reduced risk of contamination or sample loss, analysis of very small samples not separable for solution analysis, and determination of spatial distributions of elemental composition. This review describes recent research to understand and utilize laser ablation for direct solid sampling, with emphasis on sample introduction to an inductively coupled plasma (ICP). Current research related to contemporary experimental systems, calibration and optimization, and fractionation is discussed, with a summary of applications in several areas.

“…Hala ere, laginak oso homogeneoak ez badira, analisiaren adierazgarritasuna bermatzeko sakonera edota gainazal handiagoak analiza daitezke laserraren diametroa, energia eta abiadura areagotuz [7]. Horrela, laser-izpi baten erabilerak mikrolaginketa egitean informazio zehatza eskaintzen du (inklusioak, akatsak, heterogeneotasunak), laginaren gainazalean bereizmen espazial handiarekin fokatu baitaiteke [8,9]. 1. taulan ICPMS eta LA-ICPMS tekniken ezaugarriak konparatu dira .…”

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

“…Although there are many techniques used for elemental analysis in forensics, ICP-MS offers the potential for a highly sensitive, rapid, and cost effective analysis of small samples for identification and comparison of forensic evidence (27,28). Many forensically related samples have been analyzed for trace elements by ICP-MS, such as, hair (29) and nails (30), cigarettes (31), charcoal ash (32), heroin (33,34), and ginseng roots (35).…”

“…Trace and ultratrace elemental analysis by ICP-MS has also been used in many forensic analyses to determine if samples are similar to or distinguishable from one another. This technique has been used to compare various samples such as steel and glass (27), including float (36), container (37), sheet (38), and automotive (39) glass, for forensic analysis. Unfortunately, analysis of solid samples by ICP-MS requires dissolution of the sample into an aqueous solution.…”
