Bibliography

Gives methods for: - calibrating an instrument with one or two calibration gas mixtures, - determining the composition of a gas sample, and - evaluating the uncertainty of the composition of the gas sample in relation to the uncertainty of the composition of the calibration gases used and the contribution of the measurement process.
