Trace Level Quantitation of Phenyltin Compounds Using HPTLC

Abstract

The monitoring of LO, for 6-15 days has been carried out several times in the metropolitan area of Tokyo since November 1985, and data on more than 1800 samples have been obtained. Acetaldehyde, C,-C 3 alcohols, and acetone were constantly observed in chromatograms. Acrolein, C 2 -C 3 esters, propionaldehyde, C 4 C5 ethers, and methylethylketone were occasionally detected. This system has worked satisfactorily for more than 2500 hours without any exchange of parts in the devices, and has proved to be practical and durable.
