摘要：

In polymer chemistry, it is often of interest to know what are the gases evolved during the degradationof polymers. Cross-correlation chromatography (CCC) permits on-line measurements of an arbitrary number of points on the evaluation rate curve for any evolved gas component, but the rapid changes in the composition of gases generate noise in the chromatograms calculated, which might exceed the detector signal. It is shown that by using a suitable computation algorithm it is possible to suppress the correlation noise in the calculated chromatograms. Computer-simulated patterns are presented to show the usefulness of CCC in evolved gas analysis and its advantages over conventional gas chromatography in this field. © 1979.
