Effects of HCl pretreatment, drying, and storage on the stable isotope ratios of soil and sediment samples
RAPID COMMUNICATIONS IN MASS SPECTROMETRY, 30(13), 1567–1575.
RationaleStable isotope (δ13C, δ15N, δ34S values) analysis has become increasingly important for tracing contaminant sources in environments. Pretreatment of environmental samples allows accurate analysis of stable isotope ratios. The pretreatment of a sample and its subsequent preservation could either contaminate or create experimental artifacts affecting the validity of the resulting C/N ratios and the elemental isotopic contents of a sample.
