Abstract
In order to measure the mass concentration of particulate matter,according to Mie scattering theory,the relationship between scattered light flux and spherical particle diameter was discussed under the condition of polarized light input,then the formula was attained for calculating particle mass concentration by means of optical particle counter.And particle size distribution was considered using the formula to calculate mass concentration.The experimental results indicate that,in the range of 0.001mg/m3~2mg/m3,calculated mass concentration by the formula and measured mass concentration by a photometer (TSI SIDEPAK AM510) are highly correlated,the correlation coefficient is 0.9953.
