Abstract: The present invention provides a colorimetric gas detector comprising a substrate bearing a material that can react with a gas in an atmosphere being monitored and wherein the reaction causes the material to change the radiation at which the material absorbs or radiates radiation (the color-change material). The material is located in at least one discrete area of the substrate. By providing the color change material in discrete areas, the amount of such material can be reduced and different types of color-change material can be included on a common substrate to detect two or more gases simultaneously.

Abstract: A method and apparatus for gas detection uses a sensor such as an electrochemical (EC) cell and includes a feedback control loop to control a pump to establish a first predetermined gas flow rate to the EC cell. The concentration of the gas at the first predetermined flow rate is measured. If the detected concentration exceeds a predetermined Alert value at the first flow rate an Initial Warning without remedial action is generated, and, the system then changes the gas flow rate before an Alarm is indicated. An Alarm is signaled only if the system verifies the first measurement. Preferably the first flow rate is set to optimize the measurement accuracy of the EC cell being used, and the second flow rate is lower than the first. Verification of an Alarm at the first flow rate may be conducted quickly by a quick-reaction process. The controller may periodically cycle the flow rates between the first and second rates for better accuracy and faster verification times.

Abstract: Improved methods of selectively localizing, imaging and/or treating tumors, which have a net negative charge, employ novel compositions containing non-immunogenic complexes having a net positive charge in a sterile solution. The complexes contain polylysine, a linking agent bound to less than all of the lysyl groups of the polylysine, and an imaging agent or a chemotherapeutic agent which is also bound to the linking agent.

Abstract: There is disclosed a method of operating a colorimetric gas detector system that comprises a substrate (1) bearing a material (12) that can react with a target gas to produce a change in the wavelength of radiation absorbed or transmitted by the material (“color-change material”). The method involves: a) applying onto a region (15) of the substrate that includes color-change material a chemical of predetermined concentration that reacts directly or indirectly with the color-change material to produce a change in the wavelength of the radiation absorbed or transmitted by the material; b) detecting the radiation absorbed or transmitted in said region (15) at a wavelength absorbed or transmitted by the reaction product of the color change material with the chemical, and c) generating a signal in accordance with the amount of radiation detected at the second wavelength, said signal being dependent on the amount of color-change material on the substrate. The signal can be used to correct the reading of the color change material when exposed to target gas to compensate for varying amounts of color-change material on the substrate.

Abstract: An ammonia gas sensor 16 is housed within a container 14 partially immersed in a solution 2 containing ammonium ions. An electrochemical generator 6, 8, 10 generates hydroxyl ions in a region of the solution 2 adjacent the container 14. This converts ammonium ions to ammonia gas which is sensed by the sensor 16 having passed through a gas-permeable member 12. This sensing provides an indication of the concentration of ammonium ions in the solution 2.
