Pharmaceutical Impurities - Reactive Sulfurs

  
     
     
 
     
  Pictured below are two levels of standards that have been analyzed on one of the gas chromatographs dedicated for Sulfur Speciation using a Sulfur Chemiluminscent Detector (SCD). Not only can we determine total sulfur, but we go one step further, and determine which sulfurs are present and at what concentration down to a Limit of Quantitation (LOQ) of 20 ppb.
