The DPM Advantage
Impactor with precision sapphire orifices screens out interfering coal dust.
Low carbon background filters assure accurate results. Single-use cassettes are tamper-evident sealed to ensure
sample integrity.
Uses a standard personal constant flow pump such as the SKC AirChek® 2000, AirChek XR5000, or Universal XR. Flow rates of 1.7 L/min and 2.0 L/min provide optimum collection.
Meets specifications of NIOSH Method 5040 for the analysis of elemental carbon (EC) to determine total carbon (organic and elemental) in a sample. Total carbon represents more than 80% of diesel particulate emissions. Compared to gravimetric methods, NIOSH 5040 is more sensitive and specific for EC
