The Series 8900 BTEX Analyzer provides direct measurement of Benzene, Toluene, Ethylbenzene, and Xylenes in ambient air. This instrument is utilized in ambient air networks around metropolitan areas and fence-line monitoring at industrial sites. The Series 8900 BTEX Analyzer employs a photoionization detector (PID) as the sensing element. This detector is specific to volatile organic compounds. The Benzene, Toluene, Ethylbenzene, and Xylene`s in the gas sample are physically separated using proprietary GC columns.
With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.
Chemical plants that produce high quantities of phenols (plastics, pesticides and pharmaceutical industries) and other aromatic organic compounds are excellent candidates for wastewater characterization via spectral analysis. Chemicals that contain conjugated double bonds absorb UV radiation remarkably well. The benefits include higher precision in process control as well as optimization of wastewater treatment.
IntroductionVolatile organic compounds (VOCs) are a group of organic compounds which have a low vapour pressure at room temperature, meaning that they will readily evaporate into the surrounding air. The term VOC refers to many different classes of organic compounds such as alkanes, alkenes, alcohols, aldehydes, aromatics and many more.
