Analysis of natural gas — Biomethane — Protocol for the performance evaluation of gas analysers used for biomethane conformity assessment

Apstrakt

This specifies a method for determining whether an analytical system for biomethane composition analysis is fit for a defined purpose. It can be used:
a) to determine a range for each specified component over which the errors and uncertainties in measured composition do not exceed a predefined measurement requirement, using specified calibration gas(es);
b) to determine errors and uncertainties in a measured composition over a pre-defined range for each analyte, using specified calibration gas(es).
It is assumed that the analytical system is applied to compositions that vary over the typical ranges found within biomethane.
Examples specific to gas chromatography, spectroscopy and spectrometry are provided throughout the document.
