“…Polymer resin based adsorbents like Tenax TA 19 , XAD-2, XAD-4 and XAD-16 20 were used for the determination of volatile organic compounds in ambient air by many researchers in worldwide. Similarly, the carbon based adsorbents like Carbopack X 21 , Carbotrap, Carbopack B, Carbosieve-SIII and Carboxen 569 22,23 were also evaluated for the analysis of ambient volatile organic compounds. Among these, the popular resin based adsorbent Tenax TA and carbon based adsorbents such as, Carbograph 2TD, Carbograph 1TD and Carbopack X were selected for the present study to evaluate the optimal combination for the adsorption of volatile organic compounds in ambient air.…”

This study was carried out to evaluate the sampling performance and analytical methodology for the measurement of hydrocarbons in ambient air. Usually C4-C10 hydrocarbons are determined with adsorbent tube sampling and automatic thermal desorption gas chromatography coupled with mass detector (GC/MS). In this study we determined 56 compounds including hazardous air pollutants such as, benzene, toluene, ethyl benzene, xylenes, 1,3-butadiene and halogenated hydrocarbons, etc. The methodology was investigated with a wide range of different adsorbents which are commercially available and frequently adopted for the volatile organic compounds measurement. From four adsorbents are tested which are three carbon-based adsorbents such as, carbograph 2TD, carbograph 1TD and carbopack X and one polymer-based adsorbent (Tenax TA). We compare the efficiencies of the single adsorbent and multiple adsorbents with respect to volatile organic compounds adsorption. The results indicates that the most suitable combination for C4-C10 hydrocarbon measurements is triple adsorbent tube containing carbograph 2TD, carbograph 1TD and carbopack X. This method was found to be well suitable for the sampling of a broad range of volatile organic compounds in ambient air compare to the traditional methods. The sampling performance was evaluated with respect to the safe sampling volume of volatile organic compounds with a single adsorbent and multiple adsorbents for standard and field samples.

By measuring the critical current versus the applied magnetic field I c (Φ) of an Al superconducting loop enclosing a soft Permalloy magnetic dot, we demonstrate that it is feasible to design a linear magnetic flux amplifier for applications in superconducting quantum interference devices. The selected dimensions of a single-domain Permalloy dot provide that the preferential orientation of the magnetization is rotated from the perpendicular direction. By increasing an applied magnetic field, the magnetization of the dot coherently rotates towards the out-of-plane direction, thus providing a flux gain and an enhancement of the sensitivity. As a result of a pronounced shape anisotropy, the flux gain generated by the dot can be tuned by adjusting the dimensions of the dot.
