Simultaneous Determination Trace Levels of Vitamin B 1 and Vitamin B 9 in Human Samples by Ultrasound-assisted Dispersive Liquid-liquid Microextraction Coupled with Hplc-uv


Ultrasound-assisted dispersive liquid-liquid micro extraction (UA-DLLME) was proposed for simultaneous determination of trace levels of Vitamin B1 (thiamine) and Vitamin B9 (folic acid) in the human urine and serum samples. High performance liquid chromatography (HPLC) coupled with chemometrics method was employed to analysis the extraxtants. Objective: The… (More)
