Note:
 Samples requiring sulfur, which contain F, and P require an analysis or theory in order to correct the sulfur value. Samples requiring Cl and / or Br, which contain an interfering element must be analyzed by Ion Chromatography.

Sample Preparations The appropriate amount of sample is weighed accurately into an aluminum sample boat and wrapped in an ashless filter paper. The sample is combusted in a oxygen combustion flask containing hydrogen peroxide. The sample is set aside for 20 minutes.

Method Summary QTI utilizes a colormetric titration for the percentage determination of sulfur, chlorine and bromine for a wide variety of materials. Upon combustion, samples containing these elements are converted to sulfate, chloride, and bromide. Sulfate, in the presence of DMSA III, can then be titrated with barium perchlorate to a distinct blue end point. Likewise, chloride and bromide, in the presence of phenylazoformic acid 2-phenylhydrazide, can quantitatively be titrated with mercuric nitrate to a pink end point. Each titration unit is calibrated by determining a solution factor which is based on the normality of the titrant. System suitability is confirmed prior to any sample analysis by combusting and titrating an NIST traceable standard. The standard must check to within 0.4% of its theoretical value.
