Sequential measurement of δ¹⁵N, δ¹³C and δ³⁴S values in archaeological bone collagen at the Scottish Universities Environmental Research Centre (SUERC): A new analytical frontier

Rationale The use of multi‐isotopic analysis (δ 15 N, δ 13 C and δ 34 S values) of archaeological bone collagen to assist in the interpretation of diet, movement and mobility of prehistoric populations is gradually increasing, yet many researchers have traditionally avoided investigating sulphur due to its very low concentrations (<0.3%) in mammalian collagen. For this reason, and as a consequence of analytical detection limits, sulphur is...
