Environmental chamber systems are usually employed in the testing of volatile organic compound (VOC) and formaldehyde emissions from building materials.
Within daytime and nighttime collections, asterisks indicate statistical comparisons (t-tests) of volatile constituents that were significantly different (P ≤ 0.05; data shown are untransformed, but statistical analyses were performed on square-root transformed data) between plants that were exposed to the E. solidaginis emission and untreated control plants.
Antigen detection methods for the diagnosis of TB have been developed as an alternative or a supplement to microscopy, growth-based detection, antibody tests, analysis of volatile organic compounds or other biomarkers, and to immunological assays.
In addition, EVA (ethylene vinyl acetate) capmat™ as vapour barrier cover was used as reliable modification of thiazolyl blue tetrazolium bromide (MTT) assay for cytotoxicity testing of volatiles on microtiter plates.
In case of stereochemical isomers, each was tested separately, whereas racemic mixtures were used in tests with mixtures of volatile chemicals.
No "gold standard" is available for the diagnosis of LM and breath tests with measurement of volatile compounds and other gases (mainly CH4) were encouraged [ 15].
These structures were tested as sensors of volatile organic compounds (VOCs), such as acetone, benzene, ethanol and methanol in the concentration range of 10 500 parts per million (ppm).
SRB biocathode was also tested for reduction of volatile fatty acids (VFA) present in the fermentation effluent stream and the results indicated the possibility of integration of this system with anaerobic fermentation for efficient product recovery.
The aim of this experiment was to test for effects of volatile stimuli on the gustatory responsiveness of young and old pre-foraging bees.
The tests demonstrated large removal of volatile compounds like ammonia and alkyl amines.
A protocol was developed for testing the ecotoxicological effects of volatile organic compounds (VOCs) on groundwater invertebrates.
