A spcctrophotomctric channel was added to a regular flame ionization detector and used to determine several volatile organometallics. The minute flame proved capable of exciting a number of atomic species well enough for analytical ends. Both air-rich and hydrogen-rich flames were tested to establish relevant analytical parameters including vertical emission profiles. The hydrogen-rich flame was the preferable one, with sensitivities in the lower nanogram ranges for iron, tin and lead compounds, and strong discrimination against hydrocarbons.

A system for the detection of radioactive effluents from a, gas chromatograph is described. The effluents are continuously dissolved in a stream of scintillator solution. After most of the carrier gas has been split off, the solution is led at a constant rate through a helical flow cell inserted in
Tall oil is a by-product obtained from the southern kraft pulping process. In order to isolate and detect the odor compounds in tall oil, we concentrated the volatiles, using a gas-phase stripping and adsorption on a thermally stable porous polymer. The volatiles were thermally desorbed onto a high-
