FILM BADGE FOR DETERMINING CARBONYL COMPOUNDS |
摘要 |
A method for the determination of fluidic-contained aldehydes. The method comprises bringing into contact said aldehyde and a chemically inert substrate having adhered to the surface thereof a substantially monodisperse system of particles of a derivatizing agent for the aldehydes thereby forming nucleating crystals; treating said nucleating crystals with a metastable supersaturated solution in which said nucleating crystals can grow; growing said nucleating crystals to form an optically measurable film of crystals; and optically measuring said film of crystals to determine the concentration of fluidic-contained aldehydes. |
