    Abstract

    Radio frequency interference (RFI) from available frequencies in the 150 to 170 mHz band has been identified as affecting the analysis of a vapor sample using an Alco-Analyzer® gas chromatograph. Various effects on the recording of the ethyl alcohol concentration curve are discussed and demonstrated for identification of rf-induced changes.
