| Analysis Note: | For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.: • Transmission electron microscopy (TEM) • Scanning electron microscope • Light microscopy • Coulter™ counter with MDF-system Calibration of equipment is carried out with NIST-respectively BCR-particle size standards. |
| Application: | Used to calibrate, validate and monitor the performance of particle sizers, surface scanning equipment and particle counters. Monodisperse polystyrene latex particles are also used to investigate their effect on laser-induced breakdown spectroscopy (LIBS) emissions. |
| Features and Benefits: | • Suitable for routine instrument calibration checks and corrections • Available in 5 mL pack size as a neat sample |
| General description: | Polystyrene-based monodisperse microparticles (size: 2 μm) are a particle size reference standard, ideal for determining the particle size distribution (PSD) profile of test samples. |
