The procedural blank is reduced to 2.6 +/- 0.6 mu g C, with Fm of 0.42 +/- 0.10 and delta C-13 of -28.43 +/- 1.19 parts per thousand. The throughput is improved from one sample per day to two samples per day.}, issn = {0033-8222}, doi = {10.1017/RDC.2022.4}, url = {https://www.cambridge.org/core/product/identifier/S0033822222000042/type/journal_articlehttps://www.cambridge.org/core/services/aop-cambridge-core/content/view/S0033822222000042}, author = {Xu, Li and Roberts, Mark L and Elder, Kathryn L and Hansman, Roberta L and Gagnon, Alan R and Kurz, Mark D} }
