A simple needle-trap device (NTD) coupled with gas chromatography–mass spectrometry (GC–MS) was developed for the detection of trace levels nitrobenzene compounds (NBs) in workplace air. The NTD sorbent inside needle applied and quantification seven volatile NBs: nitrobenzene, o-nitrotoluene, m-nitrotoluene, p-nitrotoluene, o-nitrochlorobenzene, m-nitrochlorobenzene, p-ntrochlorobenzene. optimum temperature time desorption analytes were 270 °C 4 min, parameters such as sampling flow rate, breakthrough volume, storage capability also investigated. Limits ranges 1.8 × 10-4–1.1 10-3 5.9 10-4–3.6 mg m-3, respectively. proposed method successfully analysis NBs vehicle repair plants where highest detected concentration 0.11 m-3. NTD–GC–MS established present study may be generally applicable monitoring

Various hazardous volatile organic compounds (VOCs) are frequently released into environments during accidental events that cause many hazards to ecosystems and humans. Therefore, rapid, sensitive, on-site detection of VOCs is crucial understand their compositions, characteristics, distributions in complex environments. However, manual handling remains a challenging task, because the inaccessible health risk. In this work, we designed quadruped robotic sampler reach different for capturing trace using needle trap device (NTD) by remote manipulation. The captured samples were rapidly identified portable mass spectrometry (MS) within minutes. Rapid various including toxicants, chemical warfare agents, burning materials from was successfully achieved robot-MS system. On-site 83 typical examined. Acceptable analytical performances low limits (at subng/mL level), good reproducibility (relative standard deviation (RSD) < 20%, n = 6), excellent quantitative ability (R2 > 0.99), speed (within minutes) also obtained. Our results show system has performance safety, controllability, applicability, robustness under dangerous conditions.

Due to the increasing world population and consumer desire for sustainable nutritious protein sources, food industry is currently experiencing tremendous pressure develop innovative, sensorially acceptable, health-promoting plant-based products. Plant proteins, specifically pulse proteins arise as a healthy source applications. However, use of challenged by its intrinsic undesirable aroma often described beany, grassy, green. These off notes can be inherent, i.e. generated from plant metabolism, or produced during processing and/or storage encompass broad variety chemical classes. Since plays major role in acceptance eating habits due complexity, proper analytical methods must used assessment. Considering that effectiveness an method significantly influenced sample preparation step, this review focuses on techniques monitoring volatile profile their advantages, disadvantages, while concurrently highlighting potential novel technologies advancing critical application.
