NRCC marine sediment reference materials: MESS‐1, BCSS‐1, PACS‐1 and the NIST river sediment: SRM 2704 have been analyzed in replicate for lithium (Li) by flame atomic absorption spectrophotometry. Precision (% coefficient of variation) for the NRCC SRM's was <1.5%, and the NIST SRM was 4.3%. Results from replicate acid dissolution of the SRM's in Teflon bombs using boiling water and microwave heating showed no difference in Li concentration between the two methods.
