Isotope-Ratio Mass Spectrometer:It consists of a gas chromatographic detector coupled to an Isotope-Ratio Mass Spectrometer, able to measure isotopic ratio 13C/12C:
- Used gases: Helium 99,9992% (as pulling gas), liquid CO2 99,999% (as reference gas) and synthetic air (to trigger valves).
- Mass range: 44, 45 y 46 (3 collectors)
- Internal Reference Gas Precision:1s; n=10: < 1 x 10-6 δ 13C
- Precision using real breath samples: 1s; n=10: < 0,2 δ 13C
- Coefficient of variation for breath samples: 0,7 %
- Each exetainer tube containing a breath sample can be analyzed 5 times
Isotope-Ratio Infrared Spectrometer: This is an analyzing machine which detector is a non-dispersive infrared spectrometer. It is able to measure isotopic ratio 13C/12C:
- Used gases: Air
- Range of wavelength for absorption of 13CO2: (2230 – 2320) cm-1
- Range of wavelength for absorption of 12CO2: (2290 – 2390) cm-1
- Precision using real breath samples: 1s; n=8: < 0,5 δ 13C
- Coefficient of variation for breath samples: 2 % δ 13C
- Each exetainer tube containing a breath sample can be analyzed only once
Hydrogen, methane and carbón dioxide analyzers: This equipment analyses hydrogen and methane under principles of gas chromatography separation, using also a thermal conductivity detector. There are available models that detect and correct breath samples for contamination with room air and dead space during the breath collection procedure.
- Used gases: Air and calibration gas (H2, CH4 y CO2)
- Accuracy: + 2 - 3 ppm or 5% of complete scale for H2 and CH4; ± 1% CO2
- Precision: 1 ppm de H2 and 1 ppm de CH4
- Linear range: 2 - 150 ppm H2; 2 - 75 ppm CH4; 0,1 - 7% CO2
- Each exetainer tube containing a breath sample can be analyzed only once
Hydrogen analyzer: This equipment allows to measure hydrogen concentration in exhaled air. It’s a small device, easy to carry and used by a wide range of health professionals.
- Concentration range: 0 – 500 ppm
- Detecting feature: Thermal detector
- Precision (repeatability): ± 2%
- Batteries: 3 alkaline batteries AA (LR6 o equivalent)
- Running ambient temperature: 0 – 40ºC (storage, 0 – 50ºC)
- Running relative humidity: 10 – 90% (storage, 0 – 95%) without condensation
- Detector’s sensitivity: 1 ppm
- Dimensions: Aprox. 44 x 37 x 138mm
