  • Methods of removing inorganic fluoride from compositions containing fluorinated organic compounds
    Patent number: 11919788
    Abstract: Methods of treating a water sample containing both free fluoride and fluorinated organic compounds are described. The methods are effective at removing high amounts of the free fluoride while retaining high amounts of the fluorinated organic compounds. The methods include combining the water sample with a hexaalkyldisiloxane, a strong acid and a compatibilizing solvent; reacting the free fluoride with the disiloxane; and removing the fluorinated reaction product.
    Type: Grant

  • Oxy-pyrohydrolysis system and method for total halogen analysis
    Patent number: 11360064
    Abstract: Oxy-pyrohydrolysis articles, systems and methods for total halogen, in particular fluorine analysis are provided. A sample containing halogen elements is provided into a pyrotube for combustion. A combustion-enhancing bed including ceramic fibers or fabrics is disposed inside the pyrotube to enhance the combustion and protect the pyrotube from damage by corrosive gases.
