Analysis of Biogenic Volatile Organic Compounds in Air Using a Solid-Phase Extraction-Type Collection Device

Abstract

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 for BVOCs was quantitatively evaluated at 35°C with different volumes of air samples. The device showed good retention performance for the investigated BVOCs, that is, no breakthrough occurred for monoterpenes up to an air sampling volume of 150 L or for sesquiterpenes up to a sampling volume of 30,000 L. The elution performance was evaluated by passing organic solvents into the collection device, and an excellent elution recovery was obtained with 10 mL dichloromethane. Finally, the analytical method using the collection device was applied to determine the gaseous monoterpenes and sesquiterpenes from a grated carrot and the air inside a wooden house, and the results demonstrated the applicability of the method for the quantitative determination of BVOCs in several sample matrices.

Quantitative Determination of Gaseous Alkanes Adsorbed on Filter Paper During PM2.5 Sampling

“…Gas chromatography (GC) is most widely used method for analyzing volatile organic compounds (VOCs) [5,6] and semi-volatile organic compounds (SVOCs) [7][8][9] due to its high sensitivity and selectivity. To determine organic compounds in PM2.5, PM2.5 is collected on a quartz fiber filter or a Teflon (PTFE) filter by sampling atmospheric air using an air sampler.…”

Determination of Airborne Polycyclic Aromatic Hydrocarbons by HPLC Using SPE-Type Collection Device

“…To achieve simple, rapid, and quantitative elution of collected SVOCs, we introduced solid-phase extraction (SPE)-type collection devices, in which distribution-based adsorbents were used to determine sesquiterpenes [15] and PAHs [16,17]. Recently, we developed a SPE-type collection device packed with Sunpak-H, styrene-divinylbenzene polymer particles, as an adsorbent for collecting airborne terpenes [18] and PAHs [19]. The device performed well in collecting the investigated PAHs, which were rapidly and quantitatively eluted from the device with 10 mL of dichloromethane and determined by GC-MS.…”
