No. The primary influence on chloramine life is the stability of the
compound itself, which is determined by the relative proportions of chlorine
(gas or hypochlorite) and ammonium (hydroxide) used to make it. It's not a
gas, but a compound that is singularly non-volatile.

Early chloramines had a half-life of only a week to ten days or so.
According to the SF Water engineers, that has now been extended to over 5
weeks, typical, as they get the ratios right.

The aim is to prevent the chlorine from combining with other organics to
form carcinogenic trihalomethanes. The method basically seems to be to
prevent the chlorine from appearing as a gas in the first place.

It certainly will not go away with storage.
