In order to research electronic balance application in PM2.5 ~ PM10 particle "weighing method" detection. This article studied operational principle and relative merits of 3 common detection methods including TEOM analytic method, beta-ray analytic method and weighting analytic method for PM2.5 ~ PM10 according to existing standard specifications. And expounded emphatically practical application of electronic balance in PM2.5 ~ PM10 particle "weighing method" detection procedure on aspects of balance selection, environmental requirement and detection operating principle by taking the ultra-micro and micro mass particle detection system. Finally, this article summarizes problems and put forward development direction according to practical application results. Keywords-total suspended particulates (TSP); electronic balance; PM2.5 ~ PM10 weighing method I. NECESSITY OF PM2.5 ~ PM10 DETECTION Researches show that hazardness of total suspended particulates (TSP) is mainly embodied on two aspects below: On the one hand, the smaller the aerodynamic diameter, the more deeply it enters into respiratory tract. On the other hand, the smaller the aerodynamic diameter, the wider its dispersal range and the larger the influence ranges. Whereas hazardness of TSP on human and society, it’s important to solve PM2.5 ~ PM10 problem. The precondition of pollution control is to detect and measure pollution. How to instantly, accurately, effectively detect their mass concentration has been very urgent and necessary. II. CONVENTIONAL MEASURING METHOD OF PM2.5 ~ PM10
