Validation and practical performance of a new field measuring device for Diesel-Motor-Emissions at workplaces

Project No. FFFF 0153

Status:

completed 06/2000

Aims:

Controlling cancerogenous Diesel particulate matter in workplace air needs direct reading devices. Test and validation of commercially available photoelectric aerosolsensors (PAS).

Activities/Methods:

Testing of PAS in different versions under test stand and field conditions parallel to the coulometric method.

Results:

PAS is valid for controlling of air conditioning and in addition to the coulometric method for detection of time variations in DME-concentration. Reliable DME-monitoring should be possible with a combination of PAS and DC-sensor.

Description, key words:

Coulometric investigation of diesel particulate matter in workplace air is expensive and does not allow time dissolution. Commercially available photo-electric aerosol sensors (PAS) investigate only elementary carbons, but proved in test and field conditions and compared with coulometric results a validity for DME-monitoring with limitations.
