  We know from a previous paper that the reticulation of a coherent quantale
$A$ is a bounded distributive lattice $L(A)$ whose prime spectrum is
homeomorphic to $m$ - prime spectrum of $A$. In this paper we shall prove
several results on the pure elements of the quantale $A$ by means of the
reticulation $L(A)$. We shall investigate how the properties of $\sigma$ -
ideals of $L(A)$ can be transferred to pure elements of $A$. Then the pure
elements of $A$ are used to obtain new properties and characterization theorems
for some important classes of quantales: normal quantales, $mp$ - quantales,
$PF$ - quantales, purified quantales and $PP$ - quantales.
