1.2. Overview
Thank you for your purchase of the AethLabs microAeth® Black Carbon monitor. This product is the result
of many years of research and development and represents a leap forward in mobile and stationary Black
Carbon measurements. We hope that the features and capabilities of this product will enable new types of
research and scientific inquiry. Please let us know how you use the instrument and if there is anything we can
do to help.
The microAeth MA Series instruments are portable scientific instruments which measure the mass
concentration of light absorbing carbonaceous particles in a sampled aerosol. The instruments have 5
analytical channels each operating at a different wavelength (880 nm, 625 nm, 528 nm, 470 nm, 375 nm).
Measurement at 880 nm is interpreted as concentration of Black Carbon (‘BC’). Measurement at 375 nm
is interpreted as Ultraviolet Particulate Matter (‘UVPM’) indicative of organic sources such as woodsmoke,
tobacco, and biomass burning. The MA Series instruments have a number of important advancements. The
microAeth MA Series feature miniature cartridges that have a spool of filter material for particulate collection
and on-board analysis. The instrument automatically controls the advance of the tape material, moving to a
new unused spot when required. This allows the instrument to run continuously for multiple weeks or months
without human intervention. The 5 wavelength optical engine enables discrimination between organic and
elemental particles which is helpful in source identification when measuring different aerosols. The MA Series
also features the DualSpot® loading compensation method, which in real-time measures and adjusts for
differing optical properties of particles of varying age and composition.
