Sampling Information Normal procedures for volatile organic compound (VOC) collection should be followed. Analysis requires two (2) 40 ml VOC vials per compound per analysis for δ 2 H and δ 13 C or four (4) 40 mL VOC vials per compound for δ 37 Cl (i.e. if you want to analyze TCE, cis-DCE and trans-DCE in one sample for both δ 13 C and δ
During manufacture the outer vial has a glass micro-insert precisely positioned inside and this is permanently fused to the base of the outer vial. This gives a 12 mm x 32 mm microvial with a capacity of 350 microliters with a narrow reservoir with <10ul capacity. Removes the need to assemble a vial and insert prior to use.
Volatile organic compounds, or VOCs, contaminate our environment and cause negative health effects to humans when they are exposed to elevated levels. The testing of environmental samples for the presence of VOCs, including wastewater, drinking water and soil, is essential to ensure the public is safe and our environment is protected and

Lipid oxidation and the resulting volatile organic compounds are the main reasons for a loss of food quality. In addition to typical compounds, such as alkanes, aldehydes and alcohols, methyl ketones like heptan-2-one, are repeatedly described as aroma-active substances in various foods. However, it is not yet clear from which precursors methyl ketones are formed and what influence amino

Dec 5, 2007 · Volatile organic compounds (VOCs) emitted from materials during degradationcan be a valuable source of information. In this work, the emissions of furfural and aceticacid from cellulose were studied using solid-phase micro-extraction (SPME) incombination with gas chromatography-mass spectrometry. Two sampling techniques wereemployed: static headspace sampling using SPME for 1 h at 40 oC after
