- Abstract
A NEED exists for a method of detecting small amounts of chemicals in air and other gases, and in solutions, simply, and with a high degree of sensitivity. We have developed a new technique based on the concept of using waveguide phenomena in combination with chemical reactions. This technique is applicable to a wide variety of chemical reactions, including biochemical systems, provided that they cause a change in light transmittance by virtue of a change in colour, refractive index, or light scattering. Both real-time and cumulative measurements are possible.
