Method for performing a spectroscopic analysis on a polymer sample, and related articles

摘要

A sampling system for performing a spectroscopic analysis on a polymer during its production is described. The system includes a transfer tube capable of transporting the polymer from a production site to a storage site. The tube includes an entry site connected to the production site; and an exit site connected to the storage site. A transparent window is inserted into the wall of the tube, and a door or other barrier is provided to stop the flow of polymer through the tube, so that it accumulates against the window. A spectroscopic device situated outside the tube then takes a reading of the polymer through the window, to perform the desired analysis. Related methods are also described.
