- Abstract
Gas diffusion and flow injection analysis with a spectrophotometric detector has been developed for the determination of sulfide in a yeast culture solution. A detection limit (signal-to-noise ratio = 3) of 0.2 μM sulfide was achieved. A relative standard deviation of 3.4% (n=12) was also achieved for 0.5 μM sulfide. The technique is highly sensitive, accurate and precise, with low susceptibility to interferences, and allows significant reagent and instrument economy.
