Identification of volatile organic compounds of some Trichoderma species using static headspace gas chromatography-mass spectrometry
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...

متن کاملComparison of Static and Dynamic Headspace for Volatile Organic Compounds in Orange Juice
The determination of VOCs is widely used in many fields of chemistry. Two common sample preparation techniques for this analysis are static and dynamic headspace. Static headspace is a relatively simple sampling method that is dependent upon the formation of equilibrium conditions in a closed system. Dynamic headspace continually sweeps the headspace of the sample concentrating the analytes ont...
متن کاملDetermination of volatile organic compounds by headspace trap.
A new analytical method for the determination of halogenated and aromatic volatile organic compounds in groundwater, mineral water, and drinking water at concentrations ranging between 1-10000 ng/L is developed. A new type of headspace sampler that combines static headspace sampling with a trap is used, yielding very low detection limits and good repeatability without carryover effects. An unex...
متن کاملDiagnosing gastrointestinal illnesses using fecal headspace volatile organic compounds.
Volatile organic compounds (VOCs) emitted from stool are the components of the smell of stool representing the end products of microbial activity and metabolism that can be used to diagnose disease. Despite the abundance of hydrogen, carbon dioxide, and methane that have already been identified in human flatus, the small portion of trace gases making up the VOCs emitted from stool include organ...
