Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a method for preserving hydrazine standard liquid for a long term without causing any chemical variation or variation of concentration. SOLUTION: A hydrazine standard liquid 8 conditioned to a specified concentration is contained in a glass or plastic container 10 exhibiting low transmittance to UV-rays. After oxygen is purged by an inert gas 11, the container 10 is sealed completely.
