介绍国内第一台采用空气动力学透镜进样系统的质谱仪。这种系统有效地提高进样效率和检测效率。本仪器优化双光束测径装置和激光解析电离装置的空间结构,缩短气溶胶漂移空间从而提高小颗粒的检测极限。
Introduces the first mass spectrometer in China that uses an aerodynamic lens sampling system. This system effectively improves injection efficiency and detection efficiency. The instrument optimizes the spatial structure of the dual-beam diameter measuring device and the laser-resolved ionization device to shorten the space for aerosol drift to improve the detection limit of small particles.
