Dispersive Liquid-Phase Microextraction of Aromatic Amines in Water
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%.
Gulf Coast Conference: Increasing Density and Viscosity Throughput with Difficult Samples
October 19th 2023Daniel Wolbrecht, senior technical sales consultant at Anton Paar, held a workshop at the Gulf Coast Conference in Galveston, Texas, focusing on how heated autosampler units can help analyze difficult samples.
