Monitoring of mercury in ambient air

Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitativ e determination of mercury in vari ous environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/RA-915+/RA- 915Light with Zeeman background correction provides di rect real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of me rcury concentration in ambient air.

Ambient air quality monitoring at airports

To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from other sources at the airport.

Measurement of diacetyl in ambient air to monitor workplace exposure limits.

The Series 8900 Diacetyl Analyzer provides direct measurement of Diacetyl in ambient air. This instrument is utilized for environmental monitoring and to monitor workplace exposure limits. The Series 8900 Analyzer for Diacetyl employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Diacetyl and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The Diacetyl is separated from potentially interfering components on the analytical column and elute to the detector for analysis.
