DETECTING APPARATUS FOR COLORIMETRIC DETECTION AND IN-SITU DETERMINATION OF TOXIC GAS AND CHEMICALS AND A METHOD THEREOF

摘要

The present invention relates to a detection device and a detection method thereof, capable of rapidly detecting toxic gas and toxic chemicals from gas samples, liquid samples, and blood using the color change of silica particles which are surface-modified silica particles by metal cations with high sensitivity. The toxic gas and toxic chemicals are one or two or more materials selected from hydrogen sulfide, ammonia, and sulfide ions.
