凝聚粒子计数器 (CPC) TSI-3010 的粒子检测效率是针对饱和器和冷凝器之间的各种温差进行测量的。通过将温差从默认值 177℃ 增加到最大值 25℃，颗粒检测效率曲线变得更陡，并向更小的颗粒直径移动。这样，TSI-3010 CPC的50%检测效率直径从10.5 nm减小到5.7 nm，而无需改变其内部设计。在此尺寸范围内，可以通过在饱和器和冷凝器之间相应的温差下操作 CPC 来调整 TSI-3010 所需的检测下限。
Particle detection efficiences of the Condensation Particle Counter (CPC) TSI-3010 are measured for various temperature differences between saturator and condenser. By increasing the temperature difference from the default value of 177deg;C to the maximum value of 25°C, the particle detection efficiency curve becomes steeper and shifts to smaller particle diameters. In this way, the 50% detection efficiency diameter of the TSI-3010 CPC decreases from 10.5 to 5.7 nm, without the necessity to change its internal design. In this size range, the desired lower detection limit of the TSI-3010 can be adjusted by operating the CPC at the corresponding temperature difference between saturator and condenser.
