It shall be calibrated with propane gas expressed as equivalent to carbon atoms (C 1 ).\nMethane (CH 4 ) analysis:\nThe analyser shall be either a gas chromatograph combined with a flame ionisation (FID) type or a flame ionisation (FID) with a non-methane cutter type, calibrated with methane gas expressed as equivalent to carbon atoms (C 1 ).\nWater (H 2 O) analysis:\nThe analyser shall be of the non-dispersive infrared analyzer (NDIR) absorption type. The NDIR shall be calibrated either with water vapour or with propylene (C 3 H 6 ). If the NDIR is calibrated with water vapour, it shall be ensured that no water condensation can occur in tubes and connections during the calibration process. If the NDIR is calibrated with propylene, the manufacturer of the analyzer shall provide the information for converting the concentration of propylene to its corresponding concentration of water vapour. The values for conversion shall be periodically checked by the manufacturer of the analyzer, and at least once per year.\nHydrogen (H 2 ) analysis:\nThe analyser shall be of the sector field mass spectrometry type, calibrated with hydrogen.\nNitrogen oxide (NO x ) … ’ .",
