Liquid-phase microextraction of aromatic amines: hollow fiber-liquid-phase microextraction and parallel artificial liquid membrane extraction comparison. [PDF]

open access: yesAnal Bioanal Chem, 2023
Abstract Aromatic amines (AA) are carcinogenic compounds that can enter the human body through many sources, one of the most important being tobacco smoke. They are excreted with the urine, from which they can be extracted and measured. To that end, hollow fiber-liquid-phase microextraction (HF-LPME) and parallel artificial liquid membrane extraction ...

Liquid-phase microextraction in bioanalysis – How green can it be? [PDF]

open access: yesGreen Analytical Chemistry, 2022
Fundamental experiments were conducted with three-phase liquid-phase microextraction (LPME) to optimize greenness, followed by evaluation with the AGREEprep metric system. Extractions were from human plasma, and recoveries were studied for 90 different basic substances (drugs and endogenous metabolites) in the log P-range from -4.2 to 8.1.
