1. C, H, N, O, S의 안정 동위원소 비율 측정

2. CF-IRMS 버전은 Elemental Analyser(EA), H 와 O의 열분해를 위한 High Temperature(>1450oC) Carbon reduction furnace 및 Water equilibration (δD and δ18O)과 Carbonate/phosphoric acid reaction system (δ13C and δ18O in carbonates)을 포함한 다양한 샘플 준비 시스템에 연결할 수 있다.

3. CF(Continueous Flow) mode
- Element Analyzer : C, N & S 분석
- High Temperature Element Analyzer : H & O 분석
- Gas Chromatography with Nu GC-IRMS interface : C, N, H & D, O 분석
- Gas Prep System : Water Equilibration and Carbonate/Phosphoric Acid Reaction System : δD and δ18O와 δ13C and δ18O 분석 in carbonates

4. DI(Dual Inlet) mode
- Nu carb system : 미량 Carbonate 분석 - δ13C and δ18O 분석

5. Environmental application
- Trophic level in ecosystems by tracing 15N.
- Tracing animal migrations by stable isotopes 2H, 18O and 13C
- Plant science, using stable isotope tracers 15N

6. Food adulteration and provenance application
- Origin analysis : Tracing the geographic origin of olive oil using 13C, 2H and 18O ratios.
- Adulteration : Addition of sugars to honey. Addition of carbon dioxide to sparkling wines
- Plant science, using stable isotope tracers 15N

7. Earth Sciences application
- Nu Carb : Fully automated carbonate preparation system

8. Biomedical Science, Athletics and Doping application
- Stable Isotope tracers studies on muscle wastage and building in the body. Analysis of individual amino acids in muscle tissue.
- Doubly labelled water (DLW)studies to show energy use and total body water of patients.- Doping in sport: Used to detect use of anabolic steroids.

9. Oil and Gas application
- During drilling, stable isotopes can be used to determine the source of methane: i.e. is it thermogenic or biogenic? Thermogenic methane preserves 13C signature of original plant material. Biogenic methane is highly depleted in 13C.
- Also different crude oil reserves have a different fingerprint in stable isotope ratios: provenance.
