Techniques for Optimizing the Analysis of Volatile Organic Compounds in Water Using Purge-and-Trap/GC/MS Application
The analysis of volatile organic compounds in water is normally accomplished by purge-and-trap/gas chromatography/mass spectrometry. U.S. EPA Method 8260B with purge and trap sample introduction is widely used for the analysis of aqueous samples other than drinking water. This application note discusses problems that can arise and some easy solutions for them. These techniques have resulted in ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Purge and Trap GC-MS Determination of Trace Volatile Compounds in Drinking Water Using the HP 5973 Series MSD and Volatiles Interface (5965-8105E)
A system of purge and trap (P&T), gas chromatography (GC), and mass spectrometry (MS) was used to determine 84 volatile organic compounds at the ppt (parts per trillion) level targeted by EPA method 524.2. This was accomplished without the use of cryofocusing. The optimized system consisted of an HP 7695 P&T concentrator and autosampler; an HP 6890 Series GC with a volatiles interface (VI); a w...

متن کاملIdentification of Aroma Compounds of Lamiaceae Species in Turkey Using the Purge and Trap Technique
The present research was planned to characterize the aroma composition of important members of the Lamiaceae family such as Salvia officinalis, Lavandula angustifolia and Mentha asiatica. Aroma components of the S. officinalis, L. angustifolia and M. asiatica were extracted with the purge and trap technique with dichloromethane and analyzed with the gas chromatography-mass spectrometry (GC-MS) ...
