Application of Narrow-Bore HPLC Columns in Rapid Determination of Sildenafil Citrate in Its Pharmaceutical Dosage Forms
A special type of silica-based columns has been recently introduced into the market which is called narrow-bore columns. They have lower internal volume than the standard high-performance liquid chromatography (HPLC) columns and thus reduce the solvent consumption by almost 80%. A simple, accurate and environmentally friendly reversed phase- HPLC (RP-HPLC method) which could be used in ...

متن کاملProperties of monolithic silica columns for HPLC.
Monolithic silica columns and their use in high peak-capacity HPLC separations are reviewed. Monolithic silica columns can potentially provide higher overall performance than particle-packed columns based on the variable external porosity and variable through-pore size/skeleton size ratios. The high permeability of monolithic silica columns resulting from the high porosity is shown to be advant...
متن کاملPreparative Purification of Corticosteroids by HPLC; Scalability and Loadability Using Agilent Prep C18 HPLC Columns Application
Agilent Prep reversed-phase columns with different diameters displayed the nearly linear scaleup for the gradient separation of corticosteroids. The loadability of the columns was quite good with as much as 8 mg of total corticosteroid injected onto a 4.6-mm column and 320 mg onto a 30-mm column.
متن کاملRapid Analysis of the Beta Blocker Pindolol, using a USP Method with HPLC Columns Packed with Sub-2-Micron Particles
Pindolol is a beta blocker which helps to lower blood pressure and may possibly also alleviate depression. With potentially even more uses for this drug product it is important to develop faster analyses of it. Using pindolol and a USP method, this study demonstrates how use of short HPLC columns packed with sub-2-micron support particles (ZORBAX SB-CN (L10) columns) provide easy scalability to...
متن کاملReversed-Phase HPLC Separation of Water-Soluble Vitamins on Agilent ZORBAX Eclipse Plus Columns Application
A mixture of six B vitamins and vitamin C were separated on the same Agilent ZORBAX Eclipse Plus C-18 stationary phase in three different particle sizes and column dimensions: 5 μm (4.6 × by 150 mm); Rapid Resolution (RR), 3.5 μm (4.6 × 100 mm), and RR High Throughput (RRHT), 1.8-μm (4.6 × 50 mm). A simple phosphate buffermethanol mobile phase gradient was used. The method was designed to suppl...
