Fritillariae Bulbus is a precious Chinese herbal medicine that grown at high elevation and used to relieve coughs, remove phlegm, nourish the lungs. Historically, has been divided into two odourless crude drugs: Cirrhosae Thunbergii Bulbus. However, now Pharmacopoeia described five Bulbus-the new additions include Pallidiflorae Bulbus, Ussuriensis Hupehensis Because morphology of dried similar, it difficult accurately identify different types In current study, we develop method combining DNA...
Methane (CH4) and nitrous oxide (N2O) are among the most important atmospheric greenhouse gases. A gas sensor based on a tunable 7.6 μm continuous-wave external-cavity mode-hop-free (EC-MHF) quantum cascade laser (from 1290 to 1350 cm−1) cavity ring-down spectroscopy (CRDS) technique was developed for simultaneous detection of CH4 N2O in ambient air with water vapor (H2O) mostly removed via molecular sieve drying minimize impact H2O measurements. Still, due broad strong absorption spectrum...
Abstract In recent years, sulfur hexafluoride (SF 6 ) and sulfuryl fluoride (SO 2 F have been widely used as gas insulating medium fumigant, respectively, leading to an increase in their emissions. Additionally, SF will decompose into SO gas-insulated equipment due overheating discharge faults. Considering the hazards of atmosphere human health, it is essential develop accurate measurement system capable simultaneously monitoring trace amounts ambient air at application site. present work, a...
