Abstract: A carbon monoxide (CO) detection system is connected into an anesthesia gas delivery system. The system comprises, among other things, a CO sensor unit containing an inexpensive, replaceable sensor that detects the presence of CO in anesthesia, an in-line adapter that exposes the detection unit to the main stream of the gas and can be placed in a variety of different locations along the gas stream and a side-stream adapter for the removal and analysis of gas stream samples using a CO sensor unit outside of the main gas stream. There is also apparatus capable of measuring the response of the sensors to CO exposure, and data acquisition and a data processing unit for storing, processing and displaying the CO sensor response data. In a preferred embodiment there is a carbon monoxide detection system comprising a detection unit including a sensor unit and a measurement unit. The sensor unit detects carbon monoxide based on the change or rate of change of the optical characteristics of the sensor unit.

Abstract: Chromatographic species are continuously separated by displacement chromatography using an apparatus that comprises an inlet distribution manifold, a particulate bed, and a plurality of collector receptacles. The particulate bed is moved with respect to the inlet distributor manifold and the collector receptacles.

Abstract: Chromatographic species are continuously separated by either elution or displacement HPLC using an apparatus that comprises a stationary inlet distribution manifold, a stationary chromatographic bed, and mobile collector receptacles.

Abstract: Fused polynuclear aromatic compounds (PNAs) are continuously removed from a recycle oil stream in a hydrocracking process. An adsorption bed removes the PNAs from the recycle oil, a desorbing reagent removes the PNAs from the bed, and a regenerating agent regenerates the bed, all steps being performed simultaneously and continuously.
