Liquid chromatographic determination of glyphosate and aminomethylphosphonic acid residues in rapeseed with MS/MS detection or derivatization/fluorescence detection
Glyphosate and AMPA determinations in rapeseed extracts by (a) liquid chromatography with triple quadrupole MS detection (LC-MS/MS), or (b) liquid chromatography with post-column OPA derivatization and fluorescence detection (LC-FLD) were developed. Mean recoveries for glyphosate and AMPA were (a) 88.8–95.0% and 82.1–86.1%, and (b) 70.8–74.1% and 62.4–72.6%. RSD were below (a) 11% and (b) 22%. ...
متن کاملChemical derivatization and mass spectral libraries in metabolic profiling by GC/MS and LC/MS/MS.
An overview is presented of gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS), the two major hyphenated techniques employed in metabolic profiling that complement direct 'fingerprinting' methods such as atmospheric pressure ionization (API) quadrupole time-of-flight MS, API Fourier transform MS, and NMR. In GC/MS, the analytes are normally derivati...
متن کاملChemical derivatization for forensic drug analysis by GC- and LC-MS.
Utilizing chemical derivatization (CD) to improve gas chromatographic (GC) and GC-mass spectrometric (MS) analysis of drugs has been abundantly studied and widely practiced, while in liquid chromatography (LC) and LC-MS, application of CD approaches is still at an early stage. Silylation, acylation, and alkylation are common CD reactions, long adopted by GC and GC-MS (including GC-MS/MS) method...
متن کاملIdentification and Control of Impurities for Drug Substance Development using LC/MS and GC/MS
Identification and control of impurities for drug substances is a critical task in pharmaceutical process development for quality and safety. The most commonly used analytical technique for impurity analysis in drug substances and drug products is undoubtedly a chromatographic method, namely high performance liquid chromatography (HPLC). Impurity profiling is typically performed by HPLC and imp...
متن کاملAn Improved GC Method for Rapid Analysis of Valproic Acid in Human Plasma Without Derivatization
A simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (VPA) in human plasma has been developed. Total time for sample preparation and GC analysis is less than 45 min. After plasma protein precipitation, VPA was extracted into chloroform with suitable recovery. By using Stabilwax®<span styl...
