HPLC-FLD测定水中联苯胺的方法研究 摘要 Due to the limiting value of benzidine in water,high performance liquid chromatography with fluorescence detector (HPLC-FLD) was employed to try to meet the monitoring demand.For the pretreatment,two classic methods-both liquid-liquid extraction and solid...
Phenolic compounds and coumarins were analyzed using a High Performance Liquid Chromatograph with Diode Array Detector and Fluorescence Detector (HPLC-DAD-FLD), in series (Shimadzu Corp., Kyoto, Japan), equipped with an unit of quaternary solvent pumping (LC-20AT), an automatic injector (SIL-20AH...
The proposed method utilizes DES extraction followed by solid-phase extraction cleanup and ultrahigh-performance liquid chromatography coupled with fluorescence detector analysis. Recovery rates ranged from 85.5 to 99.1% for pistachios spiked with 1–8 ng/g aflatoxins, in compliance with EU regulations, ...
