Carbon Monoxide Detector

About this technology

Overview

Beckman Instruments, Inc. has introduced another technical approach to pollution detection which was used aboard skylab. This technique, developed with Ames assistance is known as nondispersive infrared spectroscopy. Previous nondispersive analyzers could not selectively distinguish between water vapor and carbon monoxide, thus necessitating water removal by another device before measurement. These analyzers also were susceptible to vibrations and other problems. New instrument which stimulates fluorescent in two carbon monoxide isotopes in two sealed cells, eliminates these problems and increases sensitivity to a tenth of a part per million.
