| Analysis Note: | For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer. |
| Application: | Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters. The polystyrene latex microbeads are also used: • to characterize sizing performance in impedance-based experiments. • to produce PS-μbead arrays by laser-induced forward transfer (LIFT) technique. • as a test standard for use in aerosol testbed to measure the sampling efficiency of aerosol inlet/manifold system |
| Features and Benefits: | • appropriate for routine equipment calibration checks and corrections • available in 5 mL pack size as a neat sample |
| General description: | Polystyrene-based microparticles (size: 8 μm) are a particle size reference standard, designed to determine the particle size distribution (PSD) profile of test samples. |
