The present work describes a rapid and sensitive method for the determination of carbon monoxide and carbon dioxide at low concentration levels, on line, in ethylene and hydrogen lines. These gases were separated in a column filled with Porapak Q, converted to methane and quantified by a flame ionization detector. Some modifications were made in the injection system and in the lines of the carrier gas. The detection limits of 2,6 ppbV and 4,85 ppbV for CO and CO2, respectively, were reached after modifications.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-19T10:02:50Z No. of bitstreams: 1 3196.pdf: 1157719 bytes, checksum: 3fbf13439c8ecaf5c92196c179c0b4e7 (MD5)Made available in DSpace on 2011-12-19T10:02:50Z (GMT).
