A Generic Method for the Analysis of Residual Solvents in Pharmaceuticals Using Static Headspace-GC-FID/MS
The determination of residual solvents in pharmaceuticals is one of the most important gas chromatography (GC) applications in quality assurance/quality control (QA/QC) in the pharmaceutical industry. Sample introduction is normally done using static headspace (SHS). In routine QC, GC with flame ionization detection (FID) is preferred, while mass spectrometry (MS) can be used for screening and ...
متن کاملAnalysis of Residual Solvents in Annatto Extracts Using a Static Headspace Gas Chromatography Method
An analytical method for the quantification of residual solvents in annatto extracts, natural food colorants, was established using a static headspace gas chromatography (HSGC) coupled with a flame ionization detector (FID). As a sample diluent in a headspace sampling, dimethylformamide (DMF) was selected owing to its high capacity for dissolving both bixin-based and norbixin-based annatto extr...
متن کاملAnalysis of residual solvents in ampicillin powder by headspace spectrophotometric method.
In this study a headspace spectrophotometric method is proposed for analysis of dichloromethane and isobutyl methyl keton (IBMK) residues in the ampicillin powder. Ampicillin is dissolved in 1 M NaOH in the vessel of an arsenic analyzer unit of an atomic absorption spectrophotometer. After 3-min stirring, the headspace has flowed by air into the flow-through cell and its absorbance is read at 1...
متن کاملEvaluation of Residual Diazinon and Chlorpiryfos in Children Herbal Medicines by Headspace-SPME and GC-FID
AbstractThe oldest method for the managing of the illness is the use of medicinal plants. The use of herbal products as the first choice in self-treatment of minor conditions continues to expand rapidly across Iran. This makes the safety of herbal products an important public health issue.Pesticides are used widely in agriculture to increase the production by controlling the harmful insects and...
