<p>An apparatus is provided for the preparation of a dilute solution of a sample of a fluid comprising a valve means communicating with a dilution means, a line to the dilution means to supply diluent thereto from a reservoir, a line in communication with the valve means to remove diluted sample from the dilution means through the valve means, a line in communication with the dilution means having a valve for connection to a supply of compressed gas thereto or for connection to atmospheric pressure flow control means to control flow of diluent from the reservoir to the dilution means, and control means for controlling operation of the valve means, the valve and the flow control means. The apparatus is useful for obtaining dilute solutions of polymer cements for subsequent composition or property determination.</p> |
