Although gas chromatography is a mature technique well suited for these applications, current instrumentation has deficiencies that limit its usage. Speed of analysis and non-portability are severe hindrances to using the bench top and portable instruments for on-site applications. This focus of this ...

PURPOSE:To enable the performing of a gas chromatography mass spectrometry using a nitrogen gas, by introducing a fraction directly into a sample ionization chamber using a melt quartz capillary column as separation column while an electron impact ionization method of about 200-500eV is performed in...
Sampling was done by a novel HS-SBSE system whereas the analysis was performed by capillary GC coupled mass spectrometric detection (HS-SBSE-GC-MS). The extraction optimization, using different experimental parameters has been established by a standard equilibrium time of 120 min at 85°C. A ...
