Separation of Polycyclic Aromatic Hydrocarbons was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (V/V) as co-organic solvent in mobile phase at 40°C. Analysis of...
A high-performance liquid chromatography (HPLC) method for the quantitation of doxycycline in bulk, tablets, and capsules after storage at -20, 5, 25, 40, 50, 60, and 70 degrees C, has been developed and validated. The samples are eluted from a micro-Bondapak C8 column (4.6x150-mm, i.d., 5-microm particle size) at 27 degrees C, with a mobile phase of acetonitrile-water-THF (29.5:70:0.5, v/v/v),...
results under the above chromatography condition, biuret compound (peqb) and the internal standard were detected at 4.5 and 13.5 minutes, respectively. limit of quantitation of the peqb was 0.1 µg/ml. accuracy of the method over the concentration range of 0.1-100 µg/ml was between 88-109%. inter- and intraday precisions were 4-19% and 6-8%, respectively. a good relationship in the form of a pow...
Several in vitro methods have been tested for their ability to predict drug penetration across the blood-brain barrier (BBB) into the central nervous system (CNS). In this article, the performance of a variety of micellar liquid chromatographic (MLC) methods and immobilized artificial membrane (IAM) liquid chromatographic approaches were compared for a set of 45 solutes. MLC measurements were p...
