Abstract: The invention relates to a method for determination of ambient mineral dust concentration based on optical absorption of particles concentrated by a virtual impactor as well as a device performing the said method. The method comprises the following steps:
Sampling air samples with particle size smaller than 1 μm (PM1) and sampling air samples with particle size up to 10 μm;
Concentrating the samples with particle sizes up to 10 μm with a virtual impactor;
Measuring optical absorption of collected samples at least one wavelength from UV to IR spectre, preferably from 370 to 950 nm, most preferably at 370 nm;
Subtracting the absorption of the samples with particle size smaller than 1 μm from the absorption of the sample concentrated by the virtual impactor.

Abstract: The present invention belongs to the field of systems adapted for detection and quantification of carbonaceous aerosol. It relates to an improved heating chamber for a device for measuring carbonaceous aerosol, the chamber comprising at least: an upper part and a lower part with a ring for closing and holes for pins through which heaters receive the voltage needed for heating; an inlet for leading the sampled air to a filter and a system of valves, which regulates the sampled air flow and air flow during the analysis; two heaters encasing the filter, each heater comprising at least a housing and a heating wire, wherein the first heater is installed in the upper part and the second heater is installed in the lower part, wherein the distance of the heaters from the filter is from 1 to 10 mm, and wherein the heaters are controlled with electronics; and an outlet for leading the created CO2 towards a CO2 detector.

Abstract: An apparatus and method are presented for the analysis of materials. The apparatus includes two or more similar analyzers, with the output of the analyzers combined to provide improved measurements. The apparatus may be, for example, a differential photometric analyzer, such as the AETHALOMETER®. The apparatus includes a processor programmed to accept an instrument constant determined at low filter loadings and use the constant to compensate for non-linear instrument responses. A method is also presented for conditioning filters before use.
