microAethalometer™ / MA600

Tech specs

Measurement Method
Real-time Aethalometer® method, 5 wavelength absorption analysis by measuring the rate of change of transmitted light due to continuous particle deposition on filter. Measurement at 880 nm interpreted as concentration of Black Carbon (‘BC’). Measurement at 375 nm interpreted as Ultraviolet Particulate Matter (‘UVPM’) indicative of woodsmoke, tobacco, and biomass burning.
Measurement Wavelengths
880 nm, 625 nm, 528 nm, 470 nm, 375 nm
DualSpot® Loading Compensation
Real-time analysis by measuring the rate of change in absorption of transmitted light due to the continuous collection of aerosol on filter. Simultaneous collection on two spots in parallel at different flow rates.
Timebases
1, 5, 10, 30, 60, or 300 seconds
Flow Rates
Internal long life brushless diaphragm pump provides 100, 125, 150, 170, 200, 225, 250, 275, or 300 ml/min.
Measurement Range
Per sampling location, 0-1 mg BC/m3, filter sampling location lifetime dependent on concentration and flow rate setting, decreasing proportionally with lowest wavelength optical source enabled:
IR only mode, average 5 μg BC/m3 for 24 hours at 100 ml/min
IR only mode, average 100 μg BC/m3 for 3 hours at 50 ml/min
IR only mode, average 1 mg BC/m3 for 15 minutes at 50 ml/min
Measurement Resolution
0.001 μg BC/m3
Limit of Detection
30 ng BC/m3, 5 min timebase., 150 ml/min flow rate, SingleSpot ™
