Volatile organic compounds (VOCs) in wastewater: Recent advances in detection and quantification

Enhanced acetone gas-sensing characteristics of Pd–NiO nanorods/SnO2 nanowires sensors

“…2,3 Concentrations of VOCs can be measured using standardized methods such as gas chromatography mass spectrometry, high-performance liquid chromatography, and proton transfer reaction mass spectrometry. 4 These techniques have high sensitivity and precision for detection of various VOCs. 1,4 Nevertheless, they are bulky, complex, expensive, time consuming, and need skilled operators for monitoring gases.…”

“…4 These techniques have high sensitivity and precision for detection of various VOCs. 1,4 Nevertheless, they are bulky, complex, expensive, time consuming, and need skilled operators for monitoring gases. Therefore, there is a need for small, portable, and fast dynamic devices that can easily detect acetone vapor.…”

Membrane-Based Pulsed Sampling Method for Extended Dynamic Range of Ion Mobility Spectrometry

“…Although the three methods for detecting VOCs have good performance in terms of sensitivity, limit of detection, and dynamic detection range [12,13], they all suffer from poor specificity. The response is a weighted sum of all of the responsive chemicals in the introduced sample, and the sensor is unable to specify individual compounds from complex mixtures.…”
