MSDS: Polystyrene Latex Microspheres, 20-900nm, PSL Spheres, polystyrene latex beads, calibration using polymer microspheres as particle size standards

 

PSL Spheres are excellent for use with any application that requires a NIST traceable size standard with a very narrow peak standard deviation. These PSL Size Standards are highly uniform polystyrene spheres calibrated within nanometers with NIST traceable methodology. One nanometer is 0.001 µm or 10 Angstroms. Polystyrene latex beads are used to produce PSL Wafer Standards to calibrate KLA-Tencor SP1, KLA-Tencor SP2, KLA-Tencor SP3, as well as Hitachi wafer inspection systems, SSIS. PSL Spheres are also used to create aerosol size standards for calibration of size response of laser particle counters and condensation particle counters. Size calibration or wafer inspection systems, also referred to as SSIS or Surface Scanning Inspection Systems is a major requirement in the semiconductor industry. polystyrene latex beads and PSL spheres are also used in laser light scattering studies and colloidal systems research. The 20 nm to 900 nm range of spheres is convenient to support clinical studies for checking the sizes of bacteria, viruses, ribosome and sub-cellular components. Polystyrene latex beads and PSL spheres are available as uniform polymer spheres in a range of discrete sizes from 20 to 900 nanometers (nm), and also available from 1 micron to 160 microns. The spherical diameters are calibrated with linear dimensions transferred from NIST. Spheres are used instead of irregularly shaped particles to minimize the response of laser scanners which are sensitive to shaped particles. The standards are packaged as aqueous suspensions in 15 milliliter (mL) dropper-tipped bottles. The particle concentrations are optimized for ease of dispersion and colloidal stability. The spheres have a density of 1.05 g/cm3 and an index of refraction of 1.59 @ 589 nm, measured at 25 degrees centigrade. Each bottle of PSL spheres contains a Certificate of Calibration and Traceability to NIST which includes a description of the calibration method and its uncertainty, and a table of chemical and physical properties. Polystyrene latex beads are lot-numbered for convenient technical service and support after the sale.
