title: Spectroscopy in separated flames-I. The use of the separated air-acetylene flame in thermal emission spectroscopy.
abstract: The separation of a premixed air-acetylene flame is described. The interconal zone of this flame exhibits very low radiative background, and is only slightly cooler than that of a normal air-acetylene flame. The use of the separated flame in flame photometry, for which it has several pronounced advantages, has been investigated.
