In separate inhalation experiments with coumarin and with alpha-terpineol the corresponding concentrations were 7.7 ng/mL and 6.9 ng/mL, respectively. Using tiglinic acid benzyl ester as the internal standard the following concentrations in serum could be found: alpha-santalol 6.1 ng/mL, beta-santalol 5.3 ng/mL and alpha-santalene 0.5 ng/mL. Jirovetz, L Buchbauer, G Jäger, W Woidich, A Nikiforov, AĪfter inhalation experiments with sandalwood oil and the pure fragrance compounds coumarin and alpha-terpineol, substances were detected and measured in the blood samples of test animals (mice) using gas chromatography/mass spectrometry ( GC/MS) (MID) in connection with GC/FTIR (SWC), GC/AES (carbon and oxygen trace) and flame ionization detection/ gas chromatography. Fatty acids were extracted with chloroform: methanol mixture then methylated with sodium methoxide and fractionated using.Īnalysis of fragrance compounds in blood samples of mice by gas chromatography, mass spectrometry, GC/FTIR and GC/AES after inhalation of sandalwood oil. ClausenĪ preliminary study to evaluate naturally durable wood species in an above ground field trial using Gas Chromatography-Mass Spectrometry ( GC-MS) detected differences in fatty acid extractives between species and within the same species over time. Gas chromatography-mass spectrometry ( GC-MS) analysis of extractives of naturally durable wood We describe an efficient and rapid gas chromatography/mass spectrometry ( GC/MS) method for comprehensive drug screening in urine which utilizes a liquid-liquid extraction, sample concentration, and analysis by GC/MS. Mass spectrometry, gas or liquid, can screen for hundreds of drugs and is often considered the gold standard for comprehensive drug screening. Other laboratories use a combination of various techniques such as immunoassays, colorimetric tests, and mass spectrometry to provide more detailed comprehensive drug screening. Some laboratories use only automated chemistry analyzers for limited screening of drugs of abuse and few other drugs. Ramoo, Bheemraj Funke, Melissa Frazee, Clint Garg, Uttamĭrug screening is an essential component of clinical toxicology laboratory service. Ĭomprehensive Urine Drug Screen by Gas Chromatography/Mass Spectrometry ( GC/MS). Mass spectra obtained by fused silica capillary gas chromatography/mass spectrometry/data system ( GC/MS/DS) analysis of mixtures of organic chemicals adsorbed on Tenax GC cartridges was subjected to manual and automated interpretative techniques.
