Stationary and mobile measurements using on-line instruments and chemical analysis of volatile organic compounds (VOCs) were carried out to identify the source.
In this article we propose that other on-line instruments, such as NIR probes and on-line HPLC, should be used to make more reliable and flexible software sensors.
A variety of methods and instruments are available, which range from filter-based sample collection for off-line laboratory analysis to on-line instruments that detect the airborne particles and generate size distribution and chemical data in real time.
This gives rise to various futures applications from on-line instruments to harness the so-called "wisdom of crowds", to extended endeavors in aggregating expert judgments on highly uncertain matters.
An automated on-line instrument has been developed to rapidly measure groundwater velocity within a screened well.
The authors administered Fleming's (2001) on-line instrument to N = 691students to determine student learning styles (Q1).
For this comparison a new and fast on-line instrument was built and characterized to quantify ROS in aerosol particles with high sensitivity and a limit of detection of 4 nmol H2O2 equivalents per m3 air.
ML has contributed to the development of on-line survey instruments for young people and parental survey, and to the creation of the study database.
During all experiments an on-line imaging instrument was applied to obtaining real-time images for the purpose of qualitative comparison with model predicted shape distribution.
The Steam-Jet Aerosol Collector-long Pathlength Absorbance Spectroscopy (SJAC-LPAS), an on-line continuous instrument for mobile measurements of spatial distribution of water-soluble hexavalent and trivalent chromium in ambient aerosols, has been developed and is presented here.
The same TPD principle was also tested using a Fourier transform infrared spectrometer as an analytical instrument, and the results showed that it was possible to obtain a separation of similar compounds, such as hexane and heptane, and still retaining the same sensitivity as the original on-line FTIR instrument.
