Recent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review
Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...
متن کاملDevelopment of a Method Based on the Needle-trap Microextraction Filled with Hydroxyapatite and Polyaniline Nanocomposite for Determination of Volatile Organic Compounds in the Air
In this study, the efficiency of packed needle trap with hydroxyapatite/polyaniline (NTD-HAP/PA) nanocomposite was assessed in air sampling and analysis of a hazardous group of VOCs such as benzene, toluene, ethylbenzene and xylenes. The effects of main parameters, including desorption temperature and time, were evaluated on the performance and carryover of prepared NTDs. Moreover, the repeatab...
متن کاملA headspace needle-trap method for the analysis of volatile organic compounds in whole blood.
Needle trap devices (NTDs) are a relatively new and promising tool for headspace (HS) analysis. In this study, a dynamic HS sampling procedure is evaluated for the determination of volatile organic compounds (VOCs) in whole blood samples. A full factorial design was used to evaluate the influence of the number of cycles and incubation time and it is demonstrated that the controlling factor in t...

متن کاملAnalysis of Biogenic Volatile Organic Compounds in Air Using a Solid-Phase Extraction-Type Collection Device
In this study, the quantitative determination of gaseous biogenic volatile organic compounds (BVOCs) including monoterpenes and sesquiterpenes was accomplished using a solid-phase extraction-type collection device. The collection device was fabricated by packing styrene-divinylbenzene polymer particles into a specially designed glass cartridge. The retention performance of the collection device...
