Abstract: | A combination of thermal conductivity detectors with capillary columns is used for on-line analysis of the products from a micropolit plant for the study of carbon monoxide hydrogenation. The system includes an automatically operated heated tenport sampling valve, a HP-5890-A gas chromatograph fitted with two capillary columns and thermal conductivity detectors, and a logging/controlling system. The single column design means that two analyses can be done simultaneously in one chromatograph and offers high versatility with the possibility of combining different capillary columns to cope with the needs of variable process conditions and catalyst selectivities. |
