title = "Development of an optical particle counter for high particle number concentration",
abstract = "The upper limit of the particle concentration that current optical particle counters (OPC) can detect is generally lower than 100 P/cm3, while the particle concentration in industry gas is usually on the order of 104 P/cm3. In the present study, the reasons that the current OPC is limited for high particle concentration were analyzed, and a new high-concentration optical particle counter was developed. The reasons for the low detection limit of the current OPC are as follows: (1) the thickness of the laser is on the order of millimeters; (2) the current signal processing method by detecting the rising edge is sensitive to coverage loss. Based on this, the thickness of the sheet laser was reduced by optimizing the beam shaping components, and the coverage loss of traditional signal processing methods was overcome by counting the pulse peaks. After developing the new OPC, it was used to detect particles with different concentration, and the detecting results were compared with the counting results of a commercial condensation particle counter.",
