High-performance Liquid Chromatography Separation
A h igh-per formance l i q u i d chromatography (HPLC) method has been deve loped f o r t h e s e p a r a t i o n of o l e f i n , s a t u r a t e , and a r o m a t i c hydrocarbons found i n h i g h b o i l i n g d i s t i l l a t e s and r e s i d u e s of s h a l e o i l and i n whole s h a l e o i l s . The dual-column chromatographic system uses s i l i c a g e l i n one column and s i l i...
متن کاملSEPARATION OF NONHISTONE HIGH MOBILITY GROUP (HMG) FROM HUMAN LYMPHOCYTES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...
متن کاملSEPARATION OF POLYCYCLIC AROMATIC HYDROCARBONS WITH MIXED MICELLAR HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
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...
متن کاملHigh resolution high-performance liquid chromatography separation of polyglutamic acids.
Poly-L-glutamic acids can exist in random coil, ibility because of its poor pH stability and organic helix, or sheet depending on the environmental conditions. Therefore, they have been used as molecular models for a better understanding of macromolecular stereochemistry [1]. Polyglutamylation is also the major posttranslational modiWcation of neuronal tubulin [2,3], and foliates are polyglutam...
متن کاملSimulataneous Analysis of Trimethoprim and Sulphamethoxazole Drug Combinations in Dosage Forms by High Performance Liquid Chromatography
A sensitive high performance liquid chromathography (HPLC) analytical procedure was developed for the quantitive determination of trimethoprim (TM* and sulphamethoxazole (SM) in commercial dosage forms. C18 analytical column (stainless steel, 25 cm * 4.6 mm i.d.) was packed with 5-*m particles of the reversed phase material and used for assays. Mobile phase containing 0.025 M sodium phosphate...
