Abstract
THE sensitivity of an ordinary hydrogen flame ionization detector to hydrocarbons has been found to be two to three times higher when the detector flame ‘whistles’ or ‘sings’. Further investigation of this phenomenon has disclosed the probable reasons for the enhanced sensitivity and has uncovered other useful characteristics of the singing-flame detector. ‘Singing’ hydrogen diffusion flames were first noted more than 160 years ago1, shortly after the discovery of hydrogen. A number of investigators2,3 have since investigated the characteristics of such flames; however, no practical application of this unusual phenomenon appears to have been made.
