In this report, a semi-preparative HLPC and modified SALLE based methods were optimized for the simultaneous isolation and for the HLPC-DAD determination of khat alkaloids, respectively.
By assuming he was an enlisted man because of his color, the black golfer told me, the admirals had nailed Dad's determination to send his little tiger out to dominate the world.
Dad's courage, determination and strength have shaped the people that my sister and I have become but, just as importantly, he influenced society's views on death.
Validation of the HPLC-DAD method of determination both tropicamide and apotropicamide in the tropicamide medical substance was performed.
A high-efficiency ultrasound-assisted extraction mediated by LGH-15 prior to HPLC-DAD allows the determination of 14 phenols in onion, olive, tomato and pear industrial by-products.
High-performance liquid chromatography with photodiode array detection (HPLC-DAD) was applied for determination of the drugs.
Validation of the off-line MEPS/HPLC-DAD method for the determination of six tricyclic antidepressants and their metabolites in human serum was performed.
The optimized conditions were used to develop a stability-indicating HPLC-DAD method for the quantitative determination of FEX and its related compounds in tablet dosage forms.
A method using microextraction by packed sorbent (MEPS) and high performance liquid chromatography-diode array detection (HPLC-DAD) is described for the determination of piperazine-type stimulants in human urine.
The present study describes the development and validation of a simple, rapid, selective and economical reverse phase high performance liquid chromatography-diode array detection (HPLC-DAD) method for the simultaneous determination of paritaprevir (PAR), ombitasvir (OMB), dasabuvir DAS) and ritonavir (RIT) in bulk and pharmaceutical preparations.
In the present work, the development of an analytical methodology which combines bar adsorptive microextraction with microliquid desorption followed by high performance liquid chromatography-diode array detection (BAμE-μLD/HPLC-DAD) is proposed for the determination of trace levels of four parabens (methyl, ethyl, propyl and buthyl paraben) in real matrices.
