“…Sensitivity drift in LA-ICP-MS analysis can significantly influence the accuracy and precision of the results Liu et al, 2013;Luo et al, 2007). Sensitivity drift caused by matrix differences, defocusing, and the deposition of analyzed material on the cones/lens is generally corrected by internal standard normalization.…”

LA-ICP-MS and LA-MC-ICP-MS have been the techniques of choice for achieving accurate and precise element content and isotopic ratio, the state-of-the-art technique combines the advantages of low detection limits with high spatial resolution, however, the analysis accuracy and precision are restricted by many factors, such as sensitivity drift, elemental/isotopic fractionation, matrix effects, interferences and the lack of sufficiently matrix-matched reference materials. Thus, rigorous and suitable calibration and correction methods are needed to obtain quantitative data. This review systematically summarized and evaluated the interference correction, quantitative calculation and sensitivity correction strategies in order to provide the analysts with suitable calibration and correction strategies according to the sample types and the analyzed elements. The functions and features of data reduction software ICPMSDataCal were also outlined, which can provide real-time and on-line data reduction of element content and isotopic ratios analyzed by LA-ICP-MS and LA-MC-ICP-MS.

The low‐Sr content (generally < 100 μg g−1) in clinopyroxene from peridotite makes accurate Sr isotopic determination by LA‐MC‐ICP‐MS a challenge. The effects of adding N2 to the sample gas and using a guard electrode (GE) on instrumental sensitivity for Sr isotopic determination by LA‐MC‐ICP‐MS were investigated. Results revealed no significant sensitivity enhancement of Sr by adding N2 to the ICP. Although using a GE led to a two‐fold sensitivity enhancement, it significantly increased the yield of polyatomic ion interferences of Ca‐related ions and TiAr+ on Sr isotopes. Applying the method established in this work, 87Sr/86Sr ratios (Rb/Sr < 0.14) of natural clinopyroxene from mantle and silicate glasses were accurately measured with similar measurement repeatability (0.0009–0.00006, 2SE) to previous studies but using a smaller spot size of 120 μm and low‐to‐moderate Sr content (30–518 μg g−1). The measurement reproducibility was 0.0004 (2s, n = 33) for a sample with 100 μg g−1 Sr. Destruction of the crystal structure by sample fusion showed no effect on Sr isotopic determination. Synthesised glasses with major element compositions similar to natural clinopyroxene have the potential to be adopted as reference materials for Sr isotopic determination by LA‐MC‐ICP‐MS.

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
