An improved protocol for 87 Sr/ 86 Sr by laser ablation multi-collector inductively coupled plasma mass spectrometry using oxide reduction and a customised plasma interface

Strontium concentration, radiogenic (87Sr/86Sr) and stable (δ88Sr) strontium isotope systematics in a controlled feeding study

“…Therefore feed ingredients were not specifically selected for their strontium isotope compositions prior to the experiment starting. Teeth from the feeding experiment were initially sampled as a potential 87 Sr/ 86 Sr standard for laser ablation (Lewis et al, 2014 and Eisenhauer, 2006) and that the strontium isotope composition of the pigs on mixed diets would plot between the two end members.…”

“…Sr were made following the procedure outlined in Lewis et al (2014), purified Sr was loaded onto rhenium filaments with a TaCl 5 activator (Birck, 1986). Strontium isotope ratios were measured on a Thermo-Finnigan Triton thermal ionisation mass spectrometer.…”

Differentiating mobility and migration in middle Holocene Cis-Baikal, Siberia

“…Body averages can then reflect events that are poorly related to the target of reconstruction; yielding materials formed in utero from the mother's body (and location), or strontium potentially from years earlier in development being incorporated into new tissues, suggesting that beyond a certain scale, further sub-sampling may prove challenging. Recent studies have found that micro-scale isotopic and elemental variability are sources of useful behavioral information and that micro-milled powders and laser ablation will play important roles in future research (Dolphin et al, 2012;Lewis et al, 2014;Müller and Anczkiewicz, 2016;Richards et al, 2008).…”

“…At the time, there was an unsolved problem in terms of accurately reproducing 87 Sr/ 86 Sr data for human materials using laser ablation, a problem that would eventually be identified as an isobaric interference occurring as a result of the ablation process that could be modified using post-hoc correction equations and with modification to the equipment tuning (Lewis et al, 2014;Müller and Anczkiewicz, 2016;Scharlotta et al, 2011;Simonetti et al, 2008;Woodhead et al, 2005).…”

Variation of Ba/Ca and Sr/Ca Response in Human Hard Tissue from Archaeological Series

“…The analysis of strontium, barium and calcium in bone (Burton 1996;Burton, Wright 1995) and enamel (Sponheimer et al 2005;Copeland et al 2010) has been used to reconstruct diet (Szostek et al 2009), weaning patterns (Austin et al 2013;Balter, Simon 2006;Burton, Price 1990), trophic levels in wild animals (Balter 2004), migration (Arnay et al 2009;Copeland et al 2008;Lewis et al 2014) and feeding strategies in herbivores (Sillen 1988).…”
