Chromosorb 104 is a polyaromatic-type porous resin developed by Johns-Manville for use as chromatographic packing material for gas analysis. Chromosorb 104 is the highest polarity support of the Chromosorb polymer series. It remains stable to 275°C and provides efficient separations of: • Aqueous hydrogen sulfide at low levels • Aqueous ammonia at low levels • Oxides of nitrogen Oxides of sulfur Isomeric xylenols Trace carbon monoxide and carbon dioxide
