Название (англ.):
Gas analysis; Checking of calibration gas mixtures by a comparison method
Описание (англ.):
Applies for all calibration gas mixtures stored in cylinders and permits checking of the stated concentrations of the gaseous calibration constituents. The method is based on a series of measurements by repeated preparation of mixtures having the concentration being checked, followed by a repeatability study of the analytical results at the last stage of the repetition.
