Researchers unveil method to detect 'forever chemicals' in under 3 minutes
PFAS have earned the name "forever chemicals" with good reason—the man-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
New Jersey Institute of Technology chemists have demonstrated a new lab-based method to detect traces of PFAS from food packaging material, water and soil samples in just three minutes or less.
You're viewing a single thread.
“ Chen and colleagues say the new method—involving an ionization technique for analyzing the molecular composition of sample materials called paper spray mass spectrometry (PS-MS)—is 10–100 times more sensitive than the current standard technique for PFAS testing, liquid chromatography/mass spectrometry.”
Or just answer this questionnaire I just made up:
Is that water? Yes Did you melt it from an ancient glacier? No Is it from planet earth? Yes
You’ve got microplastics flavored water!
PFAS <> microplastics, but you’re not wrong
In an attempt to be funny, I missed that! I should have known because if I’m not mistaken microplastics are super hard to measure accurately and LCMS isn’t even one of the methods used!
