Emission index for evaluation of volatile organic

Measurement of volatile organic compounds (VOCs) emitted by plants allows us to monitor plant health status without touching the plant. To bring this technique a step further towards a practical plant diagnosis technique for greenhouse crop production, we have defined a numerical index named “Emission index” to evaluate VOC emissions from tomato plants isolated from aient greenhouse air

Current Challenges in Volatile Organic Compounds …

2015-3-30 · GC-MS was shown to have ivity for VOC analysis at the ppb and low ppt levels but it needs a further preconcentration step [96, 117]. SIFT-MS allows for the measurement of trace gases at sub-ppb levels , but it is also reliable in the identifiion of compounds . The advantage of PTR-MS and SIFT-MS over GC-MS is that they do not require a

Gas detector - Wikipedia

2019-4-23 · A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is

Exhaled breath volatile organic compound (VOC) analysis for airway disease monitoring is promising. However, contrary to nitric oxide the method for exhaled breath collection has not yet been standardized and the effects of expiratory flow and breath-hold have not been sufficiently studied. These manoeuvres may also reveal the origin of exhaled compounds. 15 healthy volunteers (34 ± 7 years
