Mass spectrometer IRMS ThermoFinnigan Delta Plus XP connected to an elemental analyzer Flash EA 1112 series
Flash EA 1112 Series Delta Plus XP
Characteristics of Instrumentation:
Isotope Ratio Mass Spectrometer (IRMS) Delta Plus XP (ThermoFinnigan), installed at LSCE in 2001, coupled to an Elemental Analyzer Flash EA 1112 Series installed in 2008. This spectrometer is a Continuous Flow type spectrometer. It is dedicated to the analysis of organic matter contained in different types of samples (sediments, bones, tissues, particles in suspension, etc.). The measurement accuracy of carbon isotopes is about 0.05 ‰. The amount of carbon required for a measurement is from 20 to 40 μg for isotopic measurements and an amount of 10 to 15 mg of samples is required for elemental analysis.
Principle of Measurement:

Measurements performed by instrumentation:
Carbon and nitrogen elementary quantification and carbon isotope (δ13C) analysis of organic matter. Developing in progress of isotopic measurements of nitrogen.
