The industry standard QC/T 998-2023 for automotive cabin air filters will take effect on July 1, 2024 officially. In addition to requiring filtration performance tests in the range of 0.3 – 10 μm using A2 fine dust or A4 coarse dust, the standard also includes a requirement to test the classification efficiency of NaCl aerosols in the range of 50 – 500 nm for single-functional and multi-functional cabin air filters.
Palas® has been developing aerosol technology for 40 years and offers instruments for the generation, treatment, measurement and analysis of aerosol particles. In response to new industry standard, Palas® core product, scanning electric mobility particle size spectrometer U-SMPS 2050, can be used in conjunction with different Palas® products to provide customized solutions for different needs.
Cost-effective Choice to Meet New Standard Requirements
In response to new testing requirements, Palas® has customized a nanoparticle size classification efficiency testing system. This system includes a U-SMPS 2050, an upstream and downstream alternating sampling system, FTControl filter efficiency testing software, and other accessories such as conductive rubber hoses. The system allows users to quickly and cost-effectively achieve classification efficiency testing in the 50 – 500 nm size range using their existing test system.

This testing system can complete classification efficiency test in the 50 – 500 nm range by simply connecting the new-added Palas® instruments to the user’s existing test system. It generates reports based on the test results and retains all raw data for future reference. The U-SMPS 2050 has a measurement size distribution range of 8 nm to 1,200 nm, fully meeting the requirements of new standard. It can measure particle size and number concentration in real-time and allows for flexible selection of scan time, size range, and scan direction (upward or downward). Its excellent stability and consistency provide reliable test results, ensuring the accuracy and reliability of user testing.
