“…As it does not involve chemical separation, LA‐MC‐ICP‐MS can provide significantly faster measurements. However, many previous LA‐MC‐ICP‐MS studies only focused on samples with high Sr content (>200 ppm) and low Rb/Sr ratios (<0.02) . Even for low Rb/Sr samples, many previous LA‐MC‐ICP‐MS studies showed a 50–300 ppm shift of 87 Sr/ 86 Sr from reference values .…”

“…Although micro‐drilling coupled with TIMS can disclose the possible heterogeneity, this is also time‐consuming and the drilling diameter is large (tens of microns to several millimeters). Recently, the development of laser ablation systems connected to MC‐ICP‐MS (LA‐MC‐ICP‐MS) has made it possible to achieve fast, in situ isotope measurements . Using this technique, Sr isotope variations in plagioclase, carbonate, apatite, clinopyroxene, perovskite, fossil and basaltic glass were determined.…”

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.

Standardless fission-track dating of the Durango apatite age standard

2015

Five dating strategies were used for determining the standardless fission-track age of the Durango apatite. These use the same fossil-track densities but differ in the manner in which the induced-track densities are determined. A conventional age calculation, without correction for experimental factors, gives inconsistent ages with methodrelated differences N 15%. Correcting for these factors brings the ages in line with each other and with the reference age but leaves no room for a partial-annealing correction based on the confined-track lengths. Three further reasons suggest that a length correction is not appropriate. (1) The evidence for lengthbased corrections is inconclusive. (2) The plateau age of the Durango apatite is consistent with its apparent fission-track age to within 1%. (3) The calculated effective etchable length of the fossil tracks agrees within error with that of the induced tracks; both are further consistent with the measured mean length of confined induced tracks. The circumstance that the (U,Th)/He ages of the accepted and proposed apatite age standards are consistent with their reference ages leaves no margin for a lowered fission-track age resulting from partial annealing, although the case of the Durango apatite itself is inconclusive because of its exceptional crystal size. It is conjectured that the shortening of the fossil tacks in the Durango apatite is due to a lowering of the track etch rate over time. In this case, annealing equations fitted to induced-track data underestimate the extent of confined-track-length reduction in geological samples.
