Headspace Solid-Phase Microextraction Followed by Gas

This study provides the first assessment of the volatile metabolome map of Tuber Aestivum and Tuber Borchii originating from Greece using headspace solid-phase micro-extraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS). For the extraction of the volatile fraction, the SPME protocol was optimized after examining the effects of sample mass, extraction temperature, and

A New Method for the Fast Analysis of Trihalomethanes in Tap

Calibration standards were prepared from the stock solutions directly into 20 mL vials in a range of 0.1 to 100 g/L. The total volume of each sample was 10 mL leaving a headspace volume of 10 mL. All samples were spiked to a level of 10 g/L of the internal standard (diluted from 1 mg/L intermediate stock solution).

Evaluation of headspace-gas chromatography/mass spectrometry

As the temperature of the sample vial was increased, newly generated benzene from the headspace also increased, causing false-positive determination of benzene. Although 80 degrees C is generally accepted for the temperature of headspace sample vials, lower temperatures, such as 40 degrees C, minimize the false-positive identification of benzene.

Analysis of semivolatile organic compounds by headspace gas

Jul 16, 1993 · In this work, headspace analysis with matrix modifiers and/or high equilibrium temperatures was used to determine semivolatile components such as phenol, biphenyl, diphenyl ether, 1,3,5-triethylbenzene, 1,1-diphenylethane, and 1,2-diphenylethane in an aqueous matrix and monochlorobiphenyls in an organic matrix of moderate volatility.
