摘要： Apparatus and methods are disclosed for performing a chromatographic separation of a given compound wherein the compound and a carrier gas are passed through an injection port and onto a column and wherein a portion of the column is contained in an oven. The apparatus and method are shown to include a first heater for heating the injection port in response to a first control signal, a first temperature sensor for sensing the temperature of the injection port and for generating a first temperature signal representative of the temperature of the injection port, a second heater for heating the oven in response to a second control signal, a second temperature sensor for sensing the temperature of the oven and for generating a second temperature signal representative of the temperature of the oven and a cooling member for simultaneously cooling the injection port and the column. The cooling member can include various conduit arrangements for directing a flow of cryogen fluid. There is also shown a valve for controlling the flow of cryogen fluid through the cooling member in response to a third control signal, and a control member for receiving the first and second temperature signals, and for generating the first, second and third control signals in relation to the first and second temperature signals, so that the temperature in the injection port and the oven are maintained at a desired level.

摘要： A chemical selective sensor system utilizes admittance modulated to detect the presence of chemicals or chemical species in a fluid. The sensor system includes a film or membrane adapted to pass ions when selected chemicals which are to be detected are present at the membrane surface. The membrane is attached to a hydrophilic layer of material which, in turn, is attached to a transformed layer which is deposited on a base substrate. When the selected chamicals are present in the fluid, the membrane interacts with the chemicals to allow ions, also in the fluid, to permeate the membrane. This ion current in the membrane is transformed or converted by the transformer layer to an electronic current which is measured by an electrical circuit coupled to the transformer layer of material. An alternating current source is coupled at one terminal to the transformer layer and to the measuring circuit, and at another terminal to a circuit return electrode.

摘要： A lipid membrane is used as a chemo-receptive transducer for quantitative and semi-quantitative analysis of chemical test species in an electrolyte. The lipid membrane is contacted with an electrolyte containing the test species, and an electrical potential difference is applied across the membrane. From measurements of the trans-membrane ion current variation due to the presence of the test species, a quantitative analysis of the test species may be conducted, on a highly selective basis. Receptors showing a high degree of selectivity towards the test species are included in the membrane.
