  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • GC Analyses of Polynuclear Aromatic Hydrocarbons

    Polynuclear aromatic hydrocarbons (PAHs) can be separated by packed column or capillary column gas chromatography. An SPB-5 bonded phase fused silica capillary  column separates the 16 PAHs considered priority pollutants in wastewater by the US Pal SP-301, a liquid crystal stationary phase in packed GC columns, resolves benzo(e)pyrene and benzo(a)pyrene. This publication discusses ...
