Abstract
An embodiment provides a method for measuring an amount of total organic fluoride content of a PFAS containing sample, including: placing a sample comprising a PFAS compound in a measurement device; introducing the sample into a combustion tube, the combustion tube comprising a catalyst; oxidizing the PFAS, using heat and the catalyst, to produce a combusted sample of a plurality of measurable simpler compounds; adjusting, using a valve, a moisturization of the combusted sample; and measuring, using the measurement device, an amount of total organic fluoride of the sample after the oxidation. Other aspects are described and claimed.
Claims20
A method for measuring an amount of total organic fluoride content of a PFAS containing sample, comprising:
- placing a sample comprising a PFAS compound in a measurement device;
- introducing the sample into a combustion tube, the combustion tube comprising a catalyst;
- oxidizing the PFAS, using heat and the catalyst, to produce a combusted sample of a plurality of measurable simpler compounds;
- adjusting, using a valve, a moisturization of the combusted sample;
- and
- measuring, using the measurement device, an amount of total organic fluoride of the sample after the oxidation.
A device for measuring an amount of total organic fluoride content of a PFAS containing sample, comprising:
- a combustion tube;
- a catalyst;
- a moisturizer;
- and
- a processor;
- the device for measuring an amount of fluoride content of a PFAS compound in a sample being configured to:
- placing a sample comprising a PFAS compound in a measurement device;
- introducing the sample into the combustion tube, the combustion tube comprising the catalyst;
- oxidizing the PFAS, using heat and the catalyst, to produce a combusted sample of a plurality of measurable simpler compounds;
- adjusting, using a valve, a moisturization of the combusted sample;
- and
- measuring, using the measurement device, an amount of total organic fluoride of the sample after the oxidation.
A product for measuring an amount of total organic fluoride content of a PFAS containing sample, comprising:
- a storage device having code stored therewith, the code being executable by a processor and providing instructions to:
- introduce the sample into the combustion tube, the combustion tube comprising the catalyst;
- oxidize the PFAS, using heat and the catalyst, to produce a combusted sample of a plurality of measurable simpler compounds;
- adjust, using a valve, a moisturization of the combusted sample;
- and
- measure, using the measurement device, an amount of total organic fluoride of the sample after the oxidation.
