Abstract: An adsorbent for halogenated anaesthetics includes: an inorganic material; and an organic material providing a framework for the inorganic material. The inorganic material may be chromium and the organic material may be terephthalic acid. The adsorbent may be formed or configured such that the adsorbent includes coordinatively unsaturated sites or such that the inorganic material may form octahedral structures. The adsorbent is formed or configured to be substantially regenerated at approximately room temperature and to provide selectivity for sevofluorane in water vapour of approximately 1.0. A method of producing an adsorbent includes: selecting an appropriate chemical containing an inorganic material; selecting an organic material to provide a framework for the inorganic material; dissolving the base chemical in water; mixing the organic material with the dissolved base chemical; heating the mixture; filtering the mixture to remove excess organic material; and drying the filtrate.

Abstract: Infrared radiation from a plurality of locations associated with a process is measured by a field device, which includes a plurality of input channels, a plurality of IR sensors, and a data processor. The infrared radiation from the locations associated with the process is received by the input channels and the intensity of the infrared radiation is measured by the IR sensors to produce representative sensor signals. The data processor produces an output as a function of selected sensor signals.
