AB  - Nanomaterial particles exhibit a wide range of sizes through the formation of 
      agglomerates/aggregates. To assess nanomaterial exposure in the workplace, 
      accurate measurements of particle concentration and size distribution are needed. 
      In this study, we evaluated the performance of two recently commercialized 
      instruments: a portable scanning mobility particle sizer (SMPS) (NanoScan, TSI 
      Inc.), which measures particle size distribution between 10 and 420 nm and an 
      optical particle sizer (OPS, TSI Inc.), which measures particle size distribution 
      between 300 and 10,000 nm. We compared the data measured by these instruments to 
      conventional instruments (i.e., a widely used laboratory SMPS and an optical 
      particle counter (OPC)) using nano-TiO(2) powder as test aerosol particles. The 
      results showed obvious differences in the size distributions between the new and 
      old SMPSs. A possible reason for the differences is that the cyclone inlet of the 
      new SMPS (NanoScan) acted as a disperser of the weakly agglomerated particles and 
      consequently the concentration increased through the breakup of the agglomerates. 
      On the other hand, the particle concentration and size distributions measured by 
      the OPS were similar to the OPC. When indoor aerosol particles were measured, the 
      size distribution measured by the NanoScan was similar to the laboratory SMPS.
