We report a total evaporation negative ion thermal mass spectrometry (TE-NTIMS) technique that enables precise and accurate (±0.7‰; 2 s.d.) measurements of boron isotope ratios. The fundamental advantage of TE-NTIMS is that the effect of instrumental mass fractionation is minimised and sample signal maximised by analysing samples to exhaustion. We can analyse as little as 300 pg of B, which enables...
Values of δ 11 B reported in the literature for Holocene samples of the same foraminiferal species show large variability (6‰) relative to cited precision (<1‰). This is indicative of significant inter-laboratory biases and raises concerns about the accuracy of foraminiferal proxy pH records. To investigate this problem we have measured the δ 11 B of modern ocean carbonates using...
