查询词典 sizer

The final coated particle exiting from the condenser is then introduced into the aerodynamic particle sizer spectrometer or home-built aerosol laser time-of-flight mass spectrometer, and its aerodynamic size directly effects on the matrix to analyte molar ratio, which is very important for MALDI technique.

利用自行研制的蒸发/冷凝实验装置作为基质辅助激光解吸/电离飞行时间质谱仪的特种接口，通过冷凝方式在线添加基质，冷凝管出口处的最终粒子直接引入空气动力学粒径分析仪或自行研制的飞行时间质谱仪，可对实验室产生的生物气溶胶粒子进行实时检测。
