hi, chris ! we use nitric oxide cylinders
as standards for our NOx emissions analyzers. we get the certified
cylinders from airgas. our c of a's do not have an expiration date

Greetings listers,
Has anyone ever heard of a limited shelf-life
for cylinders of nitrogen dioxide or nitric oxide?
Both are toxic oxidizers.
Many thanks,
