Instrument Basics

The Flash IRMS Elemental Analyzer is part of the EA IsoLink CNSOH IRMS System.
The Elemental Analyzer comprises:
• Two furnaces — The left furnace, for high temperature conversion analysis, contains a silicon
carbide heater element. The heater element is immersed into a refractory material contained in a
metallic compartment. This furnace is used only for the H and O isotope ratio determinations.
The right furnace contains a quartz candle on which an electric resistance is wound.
The candle is immersed into a refractory material contained in a metallic compartment.
This furnace is used only for the N, C and S isotope ratio determination.
• Furnace Temperature Regulation — The temperature is monitored by a thermocouple of
Pt-Pt/Rh type appropriately located in the furnace.
• Furnace Cooling — The cooling time varies according to the operating temperature setting and
room temperature.
• Thermal conductivity detector (TCD) — Located in a thermostatic chamber at controlled
programmable temperature. This chamber also accommodates the analytical column.
• Chromatographic columns — The chromatographic column performs the chromatographic
separation of the reaction products generated during the combustion or high temperature
conversion process. The chromatographic column for high temperature conversion is placed in the
thermostatic chamber of the TCD detector according to the instrument configuration.
The analytical column for the combustion side (N, C and S analysis) is placed in a separate ramped
GC oven which can be heated and cooled in a fast way.
