More and more regulations regarding PFAS are being implemented with action limits that
continue to decrease. Having a harmonized method to accurately determine the PFAS content in food, as well as
other matrices, is important to ensuring long-term detection and regulation. The solvent extraction of PFAS from
these varied sample matrices can be challenging given the susceptibility to contamination and the low levels in
which these compounds are present. This poster, presented at RAFA 2024, examines the PFAS extraction several
different food samples as well as food packing matrices.
In this seventh part of " Conversations with Michael Dong," a series on fundamentals of HPLC in pharmaceutical analysis, LCGC International’s "Perspectives in HPLC" column editor explains why 2.1-mm i.d. columns are less preferred for pharmaceutical quality control.
Ultrahigh-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF-MS) shows how soaking and cooking break down soybean fats.
Nicolai Zederkopff explores chromatography’s role to help implement the maximum tolerable level (MTL) framework for food adulteration to translate analytical results into compliance decisions.
Franz Berthiller (BOKU University, Austria) discusses a multilaboratory study that used retention index markers to align mycotoxin liquid chromatography–mass spectrometry (LC–MS) data.
A QuEChERS/ultrahigh-performance liquid chromatography and high-resolution mass spectrometry (UHPLC-HRMS) method tracks 23 plant toxins in cereals and spices. Michele Suman discusses the method with LCGC International.
