A surface ionization detector for capillary gas chromatography.
A novel surface ionization detector using a reducing quartz liner and a Mo emitter with a quartz enclosed internal heater for selective measurement of alkylamines by gas chromatography is designed and evaluated.
متن کاملAnalysis of Dissolved Gases by Headspace Sampling Gas Chromatography With Column and Detector Switching. Preliminary Results
This preliminary study presents a new method for the determination of dissolved gases in sea-water. After headspace extraction, gaseous compounds are separated by GC on a dual column adsorption system. The individual species are thereafter eluted to three different detectors (thermal conductivity, flame ionization and FPD) using a second switching valve. The analysis is quantitative for methane...
متن کاملDirect analysis of artemisinin from Artemisia annua L. using high-performance liquid chromatography with evaporative light scattering detector, and gas chromatography with flame ionization detector.
Since the isolation of artemisinin 32 years ago, it has been analyzed by different chromatographic techniques. This work compared the analysis of artemisinin from crude plant samples by GC with flame ionization detection (GC-FID) and HPLC with evaporative light scattering detector (HPLC-ELSD). Data is also presented indicating that GC is suitable for the quantification of two of artemisinin pre...
متن کاملQualitative gas chromatography-mass spectrometry analyses using amines as chemical ionization reagent gases.
Ammonia is a very useful chemical ionization (CI) reagent gas for the qualitative analyses of compounds by positive ion gas chromatography-mass spectrometry (GCMS). The gas is readily available, inexpensive, and leaves no carbon contamination in the MS source. Compounds of interest to our laboratory typically yield abundant protonated or ammoniated species, which are indicative of a compound's ...
متن کاملDetermination of 2-phenylethanol in Rose Water Using Dispersive Liquid-Liquid Microextraction with Gas Chromatography Flame Ionization Detection
A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...
