Beschreibungen/Notizen

• Vacutainers that are routinely used for blood collection contain significant amounts of volatile organic compounds (VOCs). These VOCs interfere with the low parts-per-trillion analysis of VOCs in whole blood either by causing false positives or by masking the presence of VOCs because of high background levels. Benzene, bromoform, ethylbenzene, m/p-xylene, o-xylene, styrene, and various hydrocarbons are the most significant sources of VOC contamination present in the vacutainers. A method of removing VOCs from 10-mL gray-top vacutainers is presented. This method uses a combination of heat and vacuum to reduce the VOCs to levels compatible with low parts-per-trillion analysis of VOCs in whole blood.
