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 ...

A PROCEDURE has been developed for selectively increasing the responsiveness of a hydrogen flame ionization detector 1 to compounds which contain chlorine, bromine, iodine or phosphorus. The basis of ...

A method for determining the flame contour based on the flame arrival time at the fiber optic (FO) spark plug and at the head gasket ionization probe (IP) locations has been developed. The ...
