Abstract
Gas samples withdrawn from within a reactor vessel, as well as from the feed gas thereto, are passed to gas analyzers for particular components or impurities desired to be measured. The response time of the reactor analysis system employed is advantageously minimized by the elimination of dead gas space upon the closing of control valves and the provisions for rapid purging of the system or of individual gas analyzer feed lines.
