microAethalometer™ MA600 New
- 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, or 250 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
- Sensitivity
- ≈ 0.07 µg/m3 @ 1 min, 0.25 LPM (BCc, 880 nm)
- Pump Options
- Internal long life brushless diaphragm pump
