Liquid-phase microextraction of polycyclic aromatic hydrocarbons: A review [PDF]
Reviews in Analytical Chemistry, 2020 Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic compounds comprised of two or more fused benzene rings, which arise from the incomplete combustion of organic materials. These compounds have been of concern as carcinogens and mutagens

Liquid-Phase Microextraction [PDF]
, 2017 Liquid-phase microextraction (LPME) has emerged over the last 15–20 years as one of the simplest and most easily implemented techniques of sample preparation in the determination of organic analytes in a variety of matrices. This article summarizes the historical developments and various modes of the technique, method development, recent trends, and ...

Developments in liquid-phase microextraction [PDF]
TrAC Trends in Analytical Chemistry, 2003 Abstract The development of faster, simpler, inexpensive and more environmentally friendly sample-preparation techniques is an important issue in chemical analysis. Recent research trends involve miniaturisation of the traditional liquid-liquid extraction (LLE) principle by greatly reducing the acceptor-to-donor phase ratio.

Liquid-Phase Microextraction or Electromembrane Extraction? [PDF]
Analytical Chemistry, 2019 Isolation of substances by liquid-phase microextraction (LPME) or electromembrane extraction (EME) is becoming more and more important in analytical chemistry. However, the understanding of the mass transfer in LPME and EME is limited, especially for highly concentrated samples.

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