Item: Carbonaceous aerosol speciation system consisting of total carbon analyzer and aethalometer (a black carbon monitor) Item Description: Carbonaceous aerosol speciation system consisting of total carbon analyzer and aethalometer real-time complete identification and quantification of total carbon content (TC), elemental carbon content (EC), organic carbon content (OC), and black carbon content (BC) of suspended aerosol particles while providing identification of ‘Brown Carbon’ (BrC) by multi-wavelength optical analysis to separate biomass smoke from fossil fuel emissions. Requirements: 1. Total carbon analyzer must have Whatman carbon capsule and cartridge filter; basic TCA inlet plumbing fittings and tubes kit for sample air; static-dissipative tubing (3 m) with insect and water trap assembly for analytic air, VOC denuder assembly with VOC denuder cartridge and one spare; Sampler 47mm; Sharp-cut cyclone inlet (PM 2.5 at 16.7 LPM flow) kit with connection; Quartz filters – 47 mm (pack of 25), TetraCal – TCA adapter kit. 2. Aethalometer must have one roll filter tape and one cartridge filter installed in instrument; static-dissipative sample tubing (3 m); insect and water trap; flow and leak-test calibration pad; power supply cable; basic fittings set; null modern serial cable; USB stick; GMX 300 – MET sensor, 19” rack chassis. 3. First year consumables must consist of a minimum of 10x VOC denuder cartridges, 1x Cartridge filter, 1x Whatman carbon cap-75 capsule, 5x Filter tape roll, 1x Quartz filters (47 mm, 25pcs) 4. Must dry the sample stream to eliminate moisture and increase accuracy of the reading. 5. Rugged (all-steel construction is preferred) instrument package suitable for outdoor air quality monitoring applications. 6. Contains no glass and requires no gas. 7. Routine and unattended analysis of ambient aerosols. Data needs to be stored real-time with the instrument or accessed over the internet. 8. Sampling time within the range of 1 minute to 24 hours. 9. Must use ambient air as carrier gas. No catalyst involved. 10. Touch screen display on the instrument to easily access data and settings
