Researchers from the Tokyo Institute of Technology (Tokyo, Japan) used thin-layer chromatography (TLC) and high performance liquid chromatography in a study of structures on plant surfaces that provide resistance against herbivores. They examined the morphology, distribution, chemical composition, and changes during shoot and leaf development of such structures on Paulownia tomentosa, a deciduous tree native to central and western China. They used the analytical techniques to examine the chemical composition of the anti-herbivorial structures, which included bowl-shaped organs aggregated on the leaves near flower buds that secrete sugar and attract ants, glandular hairs that secrete mucilage-containing glycerides and trap small insects, and dendritic trichomes on leaves that also contain the same flavonoids as the glandular hairs.
A Review of the Latest Separation Science Research in PFAS Analysis
October 17th 2024This review aims to provide a summary of the most current analytical techniques and their applications in per- and polyfluoroalkyl substances (PFAS) research, contributing to the ongoing efforts to monitor and mitigate PFAS contamination.
Identifying PFAS in Soil Samples
October 17th 2024Jonathan Zweigle of the University Tübingen spoke with LCGC International about his work using non-targeted screening based on high-resolution mass spectrometry (HRMS) to detect PFAS in soil samples. HRMS allows scientists to determine the elemental and isotopic composition of a sample with high accuracy.
