Isoprime mass spectrometer with Elementar Elemental Analyser (EA-IRMS)

Isoprime mass spectrometer with Elementar Elemental Analyser (EA-IRMS)

The EA-IRMS also has a small CO2 laser attached. The Isoprime is a benchtop unit with a permanent magnet, to which the elemental analyser and laser have been permanently attached. The laser is plumbed through a small GC, which also has a manual injection port.

The EA functions as an on-line preparation system, which produces N2, CO2, SO2, and H2O by combustion of solid or liquid samples. Sample sizes typically range from 50-200µg for an analysis. The EA also has the ability to measure the elemental composition of a sample by using the thermal conductivity detector (TCD) or the mass spec detector. After combustion in the EA the product gases are carried via capillary in a stream of He to the mass spectrometer for stable isotope analysis.

Used for the analysis of:

• Organic C & N (kerogen, hydrocarbon fractions)
• Organic S isotopes (kerogen, hydrocarbon fractions)
• Sulfide and sulfate S isotopes
• Sulfate O isotopes
