Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The effects of laser type (Nd:YAG and excimer lasers) and their analytical parameters on S/S isotopic fractionation during LA-ICP-MS analysis were investigated. Laser fluence has a larger fractionation effect when ablating pyrite with the New Wave Nd:YAG 193 nm laser, compared to the Resonetics 193 nm excimer laser which did not produce significant fractionation over the same range of fluence (1.3-3.7 J cm). Matrix effects occurred between pyrite and bornite on both laser systems, especially at low fluence. However, matrix effects can be reduced with increasing fluence lessening the need for matrix matched reference materials. The effects of interface tubing configuration were also investigated and the addition of a 'squid' mixing device, a coil of small diameter Tygon tubing and a small volume glass bulb, was found to improve signal precision and reproducibility and decrease the washout time of the S signal between analyses. The degassing of air from the inner surfaces of the interface tubing can produce significant isotopic drift (8‰ h), hence flushing the tubing prior to analyses is crucial for reproducible analyses. The isotopic composition and homogeneity of a range of sulphide minerals were characterised for use as potential reference materials. We present preliminary data for a large, isotopically homogeneous pyrite crystal (PPP-1) which could be considered as a new isotopic reference material (δS = 5.3 ± 0.2‰).
