Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals that are widely used in consumer
products and manufacturing.
These compounds, often referred to as “forever chemicals”, are
long-lived and accumulate in the environment.
Elevated levels of these species significantly degrade
ambient air quality, posing risks to human health and the environment.
Accurate, real-time measurement
of these compounds’ chemical composition, concentration is critical for effective air quality
management.
Chemical ionization time-of-flight mass spectrometers (CI-TOF-MS) can perform the instantaneous
analysis of VOC and VICs with exceptional sensitivity, detecting levels as low as sub-parts-per-trillion,
making them suitable for real-time air quality monitoring.
In this study, we will discuss the use of CI-TOF-MS instruments for detection of PFAS.
