Abstract
The present invention is a process for cleaning a manifold which delivers high purity source chemical from a high purity source chemical container to a point of use after delivery of the high purity source chemical through the manifold is discontinued, comprising; evacuating the manifold by connection to a source of vacuum, terminating the evacuation, introducing at least one solvent for the high purity source chemical into the manifold from at least one source of the at least one solvent, dissolving any residual high purity source chemical in the manifold into the at least one solvent, venting a resulting mixture of residual high purity source chemical and solvent from the manifold, purging such as by pressurizing the manifold by connection to a source of preferably elevated pressure inert gas and terminating the purging i.e. pressurizing, before reintroducing high purity source chemical into the manifold.
