A new application of headspace single-drop microextraction technique for compound specific carbon isotopic determination of gasoline range hydrocarbons

Dispersive liquid–liquid microextraction as a novel enrichment approach for compound-specific carbon isotope analysis of chlorinated phenols

“…21 Despite the widespread use of DLLME for concentration analyses, to our knowledge no study has yet been published on its use for CSIAalthough there are some studies describing the use of other liquid microextraction techniques. 22 In this study, we used chlorinated phenols (CPs) as model compounds to evaluate the applicability of DLLME for carbon CISA. CPs are widespread environmental contaminants due to their (former) extensive use in industrial processes, for instance as precursors for pesticides or polymers and general-purpose disinfectant, especially as wood preservatives.…”

Classification of Fuel Blends Using Exploratory Analysis with Combined Data from Infrared Spectroscopy and Stable Isotope Analysis

“…As an alternative in quality control, stable isotope analysis through isotope ratio mass spectrometry (IRMS) has been used for the characterization of fuels because it provides a fingerprint based on the specific stable isotopic signature of the material. Several papers have focused on isotopic analysis of fuel and biofuel samples such as ethanol, gasoline, , methane, − crude oil, and diesel, with IRMS being applied for certification of the fuel and biofuel sources, development of new analytical procedures, and assessment of environmental remediation, among other research topics.…”
