Determination of Residual Solvents in Dapagliflozin Amorphous by Gas Chromatography with Static Head Space Method
The purpose of this research work was to develop a novel, sensitive and accurate analytical method for quantification of 12 residual solvents in Dapagliflozin Amorphous by using a static headspace gas chromatography (HSGC) coupled with flame ionization detector (FID). Methanol, Ethanol, Diethyl ether, Methyl acetate, Dichloromethane, Ethyl acetate, Tetrahydrofuran, Cyclohexane, Isopropyl acetat...
متن کاملResidual solvent determination by head space gas chromatography with flame ionization detector in omeprazole API
Residual solvents in pharmaceutical samples are monitored using gas chromatography with head space. Based on good manufacturing practices, measuring residual solvents is mandatory for the release testing of all active pharmaceutical ingredients (API). The analysis of residual organic solvents (methanol, acetone, cyclohexane, dichloromethane, toluene) in Omeprazole, an active pharmaceutical ingr...
متن کاملDetermination of residual solvents in bulk pharmaceuticals by thermal desorption/gas chromatography/mass spectrometry.
Thermal desorption (TD) techniques followed by capillary GC/MS were applied for the analysis of residual solvents in bulk pharmaceuticals. Solvents desorbed from samples by heating were cryofocused at the head of a capillary column prior to GC/MS analysis. This method requires a very small amount of sample and no sample pretreatment. Desorption temperature was set at the point about 20 degrees ...
متن کامل[Simultaneous determination of seven residual solvents in bovis calculus artifactus by headspace gas chromatography].
A headspace gas chromatography (HS-GC) method was developed for the simultaneous determination of seven residual solvents (petroleum ether (60-90 degrees C), acetone, ethyl acetate, methanol, methylene chloride, ethanol and butyl acetate) in bovis calculus artifactus. The DB-WAX capillary column and flame ionization detector (FID) were used for the separation and detection of the residual solve...
متن کاملDetermination of Residual Methylmethacrylate Monomerin Denture Base Resins by Gas Chromatography
Acrylic base resins are widely used in orthopedics and dental surgery. It is generally accepted that due to the incomplete conversion of methyl methacrylate (MMA) monomer to the polymer form during polymerization of the resin, some MMA monomers remain in the hardened material. MMA monomer has been reported to cause abnormalities or lesions in several organs of animals. Study of the literatures ...
