Qualitative and quantitative analysis of organophosphorus pesticide residues (acephate and trichlorphon) using temperature modulated SnO 2 gas sensor were studied. The testing method employed only a single SnO 2 -based gas sensor in a rectangular temperature mode to perform the qualitative analysis of pure pesticide vapor and a binary vapor mixture in the air. Experimental results...
A new rapid detecting method (called dynamic measurements) was reported to detect and distinguish the presence of two pesticide gases in the ambient atmosphere. The method employed only a single SnO 2 -based gas sensor in a rectangular temperature mode to perform the qualitative analysis of a binary gas mixture (acephate and trichlorphon) in air. Experimental results showed that high selectivity...
