BCA-2000 atmospheric particulate black carbon analyzer Introduction
The atmospheric particulate black carbon analyzer using optical attenuation method can continuously, real-time and online detect the mass concentration of carbon black aerosol in the atmosphere, and is a special instrument for monitoring carbon black aerosol. The instrument is equipped not only with a 880 nm standard light source, but also with six other reference sources (370, 450, 520, 590, 660, 950 nm), which are widely used for the measurement of black carbon mass concentration and optical absorption coefficient, black carbon aerosol. Source distribution and analysis of physical and chemical properties. Features
The technical method is in line with the standard requirements of QX/T 68-2007 Atmospheric Black Carbon Aerosol Observation - Optical Attenuation Method, and is the first and only standard recommended carbon black aerosol mass concentration measurement method.
The system is stable and reliable, self-calibrating periodically and with high accuracy.
The dual detector correction system improves the accuracy and anti-interference of the detection data; the charge integration AD system improves the detection accuracy of the multi-channel micro-current signal.
Internal high-precision flow controller and related design, stable sampling flow.
The 7-band measurement provides comprehensive optical absorption information for black carbon aerosols, which helps to eliminate the effects of interferences, and is especially suitable for scientific research applications.
