Ampoules with certified solutions (AS) contain solutions of a number of substances with a certified concentration. AS are designed for independent preparation by the consumer of certified combined-cycle gas mixtures while monitoring the quality of measurement results and the stability of calibration data. The use of AS for this purpose is prescribed in the methods of analysis FR.1.31.2014.17787, FR.1.31.2014.17955, FR.1.31.2015.20512, FR.1.31.2015.21296, FR.1.31.2016.23707, FR..1.31.2016.23997 and FR.1.31.2016.239967 for FGH chromatographs.
