Scientists from Henan Normal University (Xinxiang, China) and the University of Science and Technology Beijing (Beijing, China) developed an ultrasound-assisted ionic liquid dispersive liquid-phase microextraction procedure for determining four aromatic amines in water samples.
Scientists from Henan Normal University (Xinxiang, China) and the University of Science and Technology Beijing (Beijing, China) developed an ultrasound-assisted ionic liquid dispersive liquid-phase microextraction procedure for determining four aromatic amines in water samples. The aromatic amines — 2,4-dichloroaniline, 1-naphthylamine, 6-chloroaniline, and N,N-dimethylaniline — were analyzed after the extraction procedure by high performance liquid chromatography with UV detection. The method was used successfully to analyze real water samples, and they obtained spiked recoveries of 92.2–119.3%.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
Reflecting on the Influence of the Current State of Sample Preparation on GC, Part 2: Techniques
May 9th 2024In this installment, we examine trends in the use of sample preparation techniques through the lens of instrumental analysis by gas chromatography (GC) and GC–mass spectrometry (GC–MS).
