Evaluation of aluminum canisters for the collection and storage of air toxics

Abstract: 1899transient adsorption studies to be performed on both bare and chemically modified quartz surfaces. The use of a GC configuration coupled with the resolving power of capillary columns provides the potential for the rapid screening of chemically modified surfaces for molecular recognition. Further work in this direction is currently in progress.Registry No. IPA, 67-63-0; silica, 60676-86-0. (12) Wohltjen, H.; Dessy, R. Frank, M. D.; Heckl, W. M.; Marassi, F. M.; Vlgmond, S. J.

“…29 Testing of polar compounds 2-butanone, butanol, acetonitrile and ethanol gave percent RSD values < 20 percent under similar conditions with the exception of one test series for 2-butanone. Polar compound storage stability tests were also reported by Gholson et al 27 with mixed results.…”

“…25 ' 26 Recent storage stability studies of VOCs in polished and unpolished aluminum canisters indicate that a set of nonpolar VOCs can be stored successfully under certain conditions. 27 The compounds that have been tested include the list of 41 compounds from TO-14, as well as a number of hydrocarbons and substituted hydrocarbons (See Table I). However, variation in the experimental conditions can affect the results.…”

“…Além disso, um severo procedimento de limpeza e a minimização da área interna superficial ativa são essenciais antes do uso, para evitar as perdas por adsorção na superfície. 1,26 O tratamento da superfície interna dos canisters para redução dos sítios ativos de adsorção é conhecido como passivação e é feito geralmente através do processo SUMMA, 27 que consiste no eletropolimento do interior dos canisters, enriquecendo a superfí-cie com uma camada de óxido de Ni-Cr, tornando-a mais inerte que a superfície não tratada. Alguns trabalhos relatam a utilização dos canisters de aço inoxidável eletropolido para a coleta de DMS ou COS, seguida da análise em um intervalo de tempo menor que 1 h. [28][29][30] O canister SUMMA não é adequado para a amostragem de H 2 S e mercaptanas.…”
