A Continuous Flow Interface connects solid and liquid sample preparation devices to instruments that measure isotopic composition. It allows the introduction of the sample and also reference and carrier gases.
Examples: Finnigan MATConFlo II, ThermoScientific ConFlo IV, and Picarro Caddy.
Note: This is NOT an analyzer

Amino acid compound specific isotope analyses of abyssal deposit feeders, gut contents, and surrounding surface sediments collected on R/V Atlantis cruise AT42-10 and R/V Western Flyer Pulse 72 in the eastern North Pacific in 2019 | Carbon isotope composition of amino acids was measured using a Thermo-Fisher Scientific MAT 253 isotope ratio mass spectrometer interfaced with a Trace Ultra GC-III via ConFlo IV. | ConFlo IV (input from IRMS, output to GC) |

Carbon and nitrogen data from kelp determined during seasonal global change experiments examining the effects of seasonal variation in light availability and nutrients on the response of three high-latitude kelp species | Dried tissue was analyzed for nitrogen content and δ13C values by the UCSC Stable Isotope Laboratory using a CE Instruments NC2500 elemental analyzer coupled to a Thermo Scientific DELTAplus XP isotope ratio mass spectrometer via a Thermo-Scientific Conflo III. | Thermo-Scientific Conflo III |
Carbon and nitrogen stable isotopes of marine inorganic and organic matter around O'ahu, Hawai'i, December 2017 | Used for Dissolved Inorganic Carbon (DIC) analysis. | Thermo Finnigan Delta Plus XL continuous flow mass spectrometer and ThermoFinnigan GasBench II |
Dissolved organic matter sulfur and carbon analysis of samples collected between 2010 and 2021 from various locations globally | SPE extracts were analyzed for their C and S concentrations and stable isotope compositions (δ13C and δ34S) via combustion elemental analyzer (EA) / isotope ratio mass spectrometry (IRMS). The system comprised a Thermo Scientific Flash EA IsoLink CN, coupled to a Delta V Plus IRMS via a ConFlo IV Universal Interface. The EA was configured with dual columns (combustion: WO3 over Cu; reduction: Cu metal) and a temperature-programmable GC column oven that allows both CO2 and SO2 to be eluted in the same run, as described by Phillips et al. (2021). Due to the high C:S molar ratios of DOM, CO2 was diluted by 88.4% following combustion via the ConFlo. Urea standards were run at the same settings to account for any possible fractionation of 13C by this dilution. | ConFlo IV Universal Interface |
Results from feeding assays conducted as part of seasonal global change experiments examining the effects of seasonal variation in light availability and nutrients on the response of three high-latitude kelp species | Dried tissue was analyzed for nitrogen content and δ13C values by the UCSC Stable Isotope Laboratory using a CE Instruments NC2500 elemental analyzer coupled to a Thermo Scientific DELTAplus XP isotope ratio mass spectrometer via a Thermo-Scientific Conflo III. | Thermo-Scientific Conflo III |
Chemical analyses of size-fractionated particle samples collected during the BIOS-SCOPE cruise AE1819 in the Sargasso Sea in July 2018 | Thermo Flash elemental analyzer coupled to a Conflo IV and MAT 253 Plus isotope ratio mass spectrometer (EA-IRMS, Thermo Scientific). | Conflo IV |
Kelp growth data from seasonal global change experiments examining the effects of seasonal variation in light availability and nutrients on the response of three high-latitude kelp species | Dried tissue was analyzed for nitrogen content and δ13C values by the UCSC Stable Isotope Laboratory using a CE Instruments NC2500 elemental analyzer coupled to a Thermo Scientific DELTAplus XP isotope ratio mass spectrometer via a Thermo-Scientific Conflo III. | Thermo-Scientific Conflo III |
