Applikon has announced that its Marga system can be used to monitor aerosols and gases in ambient air.
Air pollution not only comprises gaseous components but also particulate matter (PM) in the form of tiny particles.
Marga is able to quantitatively sample PM and acidifying gases, which are then separated by a WRD (wet rotating denuder) and SJAC (steam jet aerosol collector) respectively.
The collected samples are analysed by integrated ion chromatographs.
A Marga system is also available with two sample boxes to determine size segregated composition or deposition velocities.
Features of the system include: continuous monitoring with hourly results; results on the composition of gases and aerosols; remote access and data transfer; one-week unattended operation; smart software with security and validation levels; and quality assurance of the measurement with internal standard.
