Determination of PFAS in Environmental Waters Using DHS-GCxGC-TOFMS
PEGBT4D_PFAS_ENVIRONMENTAL_WATER_203-821-721This research aimed to leverage dynamic headspace extraction (DHS) combined with thermal desorption as an alternative for the extraction of volatile and semi-volatile PFAS in water samples. Advanced analytical techniques such as gas chromatography coupled to time-of-flight mass spectrometry (GC-TOFMS) and comprehensive two-dimensional gas chromatography (GCxGC)-TOFMS were used to enhance...Access Determination of PFAS in Environmental...Determination of Oxygen in Lithium Battery Materials
203-821-723Determining the oxygen content in lithium battery materials is important because the oxygen content directly affects the structure, performance, stability, and safety of the cathode. In lithium-ion battery materials, the oxygen content is essential for peak performance, as deviations (specifically oxygen loss) result in the degradation of battery capacity, voltage,...Access Determination of Oxygen in Lithium...Investigation of Musty Malodor in Consumer Bath Towels with GCxGC and TOFMS
203-821-720In this work, we investigated the volatile and semi-volatile chemical components of used consumer towels with a goal toward exploring the musty malodors. A collection of towel swatches, some with the malodor and some without, were sampled with headspace solid phase microextraction (HS-SPME) and analyzed with GCxGC-TOFMS. There were some...Access Investigation of Musty Malodor in...Determination of Hydrogen in Aluminum
203-821-719Hydrogen gas has a high solubility in molten Aluminum and is readily introduced during processing. Once solidification begins, the solubility decreases approximately twenty-fold, and Hydrogen is forced out of the Aluminum. Although most of the Hydrogen is diffused, a small percentage may get trapped, creating Hydrogen-filled voids. This remaining Hydrogen...Access Determination of Hydrogen in Aluminum
