Application precautions

WhenH₂O、CO₂ andCH₄ When the concentration is much higher than the normal environmental level, or when there are other organic compounds, ammonia, ethane, ethylene, or sulfur-containing compounds present, the measurement may be disturbed.H₂OWhen the isotopic ratio changes significantly, it may affect the measurement results. Users should use prepared standard laboratory samples for validation. For more details about the experimental conditions, please contact us.
