Rapid and Direct Analysis of Free Phytosterols by Reversed Phase HPLC with Electrochemical Detection
Patil A.T. and Shaikh K.A. ii ABSTRACT
The modification of high-performance liquid chromatography parameters leads to a more effective oligonucleotide-A purification process. Using various experimental such as buffer, concentration, and pH, method for optimizing the an on reverse-phase C18 column was created. To purify oligonucleotide-A, High-Performance Liquid Chromatography (HPLC), Ultraviolet-Visible Spectrophotometry (UV-Vis), C...
A convenient method for the separation of molecular species of complex lipids such as sphingomyelin and ceramide by argentation high performance liquid chromatography (HPLC) is described for the first time. Molecular species separation of these complex lipids was achieved for quantitative analysis and preparative work by the combined use of argentation and reversed-phase HPLC.-Smith, M., P. Mon...
We have carried out a single-dose comparison of three different dextromethorphan cough mixtures in 10 healthy human volunteers. Dextromethorphan was administered in a single dose of 60 mg in random order. The concentrations of dextromethorphan and its main metabolite, dextrorphan, were determined from the plasma samples using high performance liquid chromatography. The concentrations of dextror...
The vapor condensation method can be used for forming an alternative flow of liquid masses using a single solvent for alternative plugs flow liquid chromatography (APFLC), described in our previous paper. APFLC is more effective when adopting a T-shaped flow path and aqueous-organic solvents with a liquid-to-gas volume ratio (bulk fraction; β) ranging between 0.0006 and 0.004 in an open tubular...
OBJECTIVE The purpose of this study was to optimise the HPLC-UV bio-analytical method currently used by the Salamanca University Clinical Hospital for determining lamotrigine plasma levels. MATERIAL AND METHODS The developed HPLC-UV analytic technique currently in use was shown to be linear, exact and precise, and suitable for use in routine monitoring of lamotrigine levels. The drawback of t...
