However, it is hard for current available classifiers to achieve nanoparticle classification at high particle mass loading conditions in addition to the cost of high pressure drop. In this study, a nanoparticle inertial classifier (NIC) was developed to classify nanoparticles without particle loading effect for the long term. The NIC operated at a 3 L/min flow rate consists of a micro-orifice plate with 163 nozzles and a wetted glass fiber filter substrate through which water is injected upward to wash off deposited particles continuously. This study is the first to achieve a 100 nm cutoff aerodynamic diameter with such a low pressure drop of 8.3 kPa for inertial classification. The NIC showed good number-based and mass-based classification performance for NaCl particles with a narrow nanoparticle size distribution. The NIC also performed well for generating stable nano-TiO2 particles with different feeding mass concentrations up to 92.18 mg/m3 during a 60-min operation. The current 3 L/min NIC thus can serve as a nanoparticle classifier with high loading mass concentration for future applications such as nanopowder classification or inhalation toxicity testing.
