| Abstract: | Estimation of dieldrin in cured tobacco using published methods of clean-up followed by electron-capture g.l.c., suffers from serious interferences. Such interference can be eliminated by Storherr sweep codistillation and t.l.c. on alumina. The limit of detection is 0.01 part/million. |
