Unique Technology with Life Saving Advantages
Scientists at the Quantum Group have successfully combined biotechnology with infrared engineering to produce reliable and false alarm-free carbon monoxide sensing elements. The Company is the first to commercialize a biotechnology-based gas sensor. Two CO sensing elements (one red and one yellow) are at the heart of the Quantum’s Solid-state Infrared (SIR) sensor. Each patented sensing element is made from a porous transparent disk coated with a monolayer of a supramolecular complex, which is a catalyst. A self-assembly process is used to construct the fast regenerating sensing elements. Upon exposure to CO, one or both of the sensing elements changes its spectral character and absorbs photons at a rate dependent on the concentration of CO in the surrounding environment. Thus by monitoring the sensing elements with patented electronics a linear response is produced. The sensing elements reverse their spectral shift by a self-regeneration process whose rate is dependent upon the decrease of CO in the environment. By monitoring the rate of change in the amount of light transmitted through the sensing elements, the concentration of CO in the surrounding environment can be determined accurately. The CO response characteristics of a particular sensor can be designed to meet specific standards or applications by controlling the formulation process. Sensing elements can be designed to satisfy customer’s needs.
