A simple, efficient and green microextraction method namely ultrasound assisted-dispersive solid-liquid microextraction based on solidification of floating organic droplet (UA-DSLME-SFOD) coupled to HPLC and UV detector was developed for preconcentration and determination of levothyroxine in human urine and serum samples.
For this purpose, this paper introduces a novel methodology based on dispersive liquid-liquid microextraction (DLLME) coupled to high performance liquid chromatography with ultraviolet detector (HPLC-UV) for the extraction and determination of organosulphur compounds in different matrices.
Solvent bar microextraction (SBME) combined with gas chromatography-flame ionization detector (GC-FID), was used for preconcentration and determination of some aliphatic amines in waste water samples.
Dispersive liquid liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detector (GC-FID) was developed for preconcentration and determination of some nitroaromatic compounds in wastewater samples.
Identification of pesticide residues and determination of their levels were performed by high-performance liquid chromatography with photodiode array detector.
Zebrafish strains, maintenance and determination of genotype.
In the present work, an inductively coupled plasma atomic emission spectrometry (ICP-AES) system was used as a high temperature liquid chromatography (HTLC) detector for the determination of alcohols and metals in beverages.
Moreover, TLC combined with densitometer or MS and also detector enables the determination of drug components in a low range: pmol or fmol.
