The occurrence of trace contaminants in gas supplies and surrounding air are a serious issue of concern for bulk gas producers, semiconductor manufacturers, plant environmental safety crew, and research scientists. The presence of pollutants can limit product quality, restrict process yields, skew research results, or point to a future environmental danger. The Trace Analytical ta5000F (Flame Ionization Detector) and the ta5000R (Reduction Gas Detector) Gas Analyzers serve as a key to this problem, as they are extremely precise from parts per million (ppm) down to low parts per billion (ppb) levels. This accuracy in union with the isolating power of gas chromatography assembles a completely unique unit. With advanced user interface features, the ta5000 is the ideal analyzer for specific analysis of pollutants in air, for pure gas quality control, research and for various other gas monitoring operations.
