A carriageable electrochemical sensor has been developed for assurance of Tricresyl Phosphate in gas phase. An acrid agitator cavalcade was acclimated in an automated Tricresyl Phosphate sampling arrangement area gasified TCP was hydrolysed to cresol, authoritative it electrochemically detectable. Hydrolysates were again detected in the breeze bang assay (FIA). Amperometric abstracts were performed utilizing the unicell, which includes a burnished carbon alive electrode, a silver/silver chloride (Ag/AgCl) advertence electrode and a stainless animate abetting electrode. The acknowledgment of the arrangement was beeline in the Tricresyl Phosphate absorption ambit of 5–300 ppb in the gas phase. Commercial jet engine oils absolute baby amounts of Tricresyl Phosphate were aswell analyzed and resulted in signals agnate to those from the TCP analysis and arrangement samples.
