Abstract:
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.
Abstract:
The present invention provides an ammonia detection device using color change and a detection method thereof. A tube or a column contains silica particles with surface modified with copper ions. The silica particles with surface modified with copper ions and ammonia are reacted in the tube or the column.

Abstract:
PURPOSE: Absorbent for collecting volatile materials from a fired place, an absorbing pipe with the absorbent, and a method for using the same are provided to improve the stability of absorption by including fullerene and charcoal. CONSTITUTION: Absorbent for collecting volatile materials from a fired place includes 7 weight% of more of fullerene and charcoal. An absorbing pipe with the absorbent is composed of a first absorbing pipe(110) and a second absorbing pipe(120). The first absorbing pipe is composed of a first connecting part(111), an expanded pipe(113), and a first tapered part(115). The first connecting part is in connection with a flexible pipe. The expanded part is next to the first connecting part. The first tapered part is next to the expanded part. The second absorbing pipe is composed of a second tapered part, a cylindrical part(125), and a second connecting part(129). The cylindrical part is next to the second tapered part. The second connecting part is next to the cylindrical part.
