What laboratories need to know about PFAS and ultrapure water quality
30 Sept 2026PFAS analysis at increasingly low concentrations requires careful control of every potential contamination source, including the water used for blanks, standards, dilutions and sample preparation.
In this expert Q&A, Dr. Kunal Kureja of Sartorius discusses why ultrapure water quality matters in sensitive PFAS workflows. The interview explores common contamination risks, relevant analytical methods, and the practical considerations laboratories should assess when selecting a water purification system.

Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
