<div>A team of researchers from the University of Kansas have developed a new, cost-effective method to accurately sample and measure per- and polyfluoroalkyl substances (PFAS). If scaled, researchers believe this could ease the burdens of intensive laboratory testing constraints for forever chemical contamination.The work was published in PLOS Water and explains the current barriers to efficiencies, citing expensive laboratory equipment necessary to testing and extensive hours of work to test concentrated samples. The solution the team found was by combining fast-flow solid-phase extraction (SPE) to concentrate PFAS-laden water samples with mass spectrometry technology to achieve efficient sensitive chemical analysis at parts-per-trillion (ppt) levels of detection.“The biggest improvement in our method is time reduction in sample concentration,” said study co-author Michael Zhuo Wang, professor of pharmaceutical chemistry at the University of Kansas. “We reduced the time from hours to minutes. For a 500 milliliter sample, it used to take about 100 minutes to load. Now it takes about 6 to 8 minutes, about a 20-fold reduction. To push detection even lower, you need larger volumes—up to 4 liters instead of 500 milliliters. That’s an eightfold increase in volume.”Wang also explained that shipping large water samples to labs from the field is a challenge, so another focus of the team’s work is developing a concentration device that can directly absorb PFAS from the water samples. For this effort, the team is working with InnovaPrep, a company formed by other college innovators, to design field testing devices that can achieve this goal to make testing more efficient and effective.</div>
