General description

Monodisperse polystyrene based micro particles (size: 30 μm) are a particle size standard, ideal for characterizing particle size distribution (PSD) of test samples.

Application

Used to calibrate and validate the performance of particle size analyzers.
Monodisperse polystyrene latex particles can also be used to:
  • validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements
  • study the size effect of polystyrene microplastics on the sorption of organic contaminants

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 mL pack size as a neat sample

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.

Pattern separation is a process that minimizes overlap between patterns of neuronal activity representing similar experiences. Theoretical work suggests that the dentate gyrus (DG) performs this role for memory processing but a direct demonstration is lacking. One limitation is the

The relationship between tickling, sensation, and laughter is complex. Tickling or its mere anticipation makes us laugh, but not when we self-tickle. We previously showed rat somatosensory cortex drives tickling-evoked vocalizations and now investigated self-tickle suppression and tickle anticipation. We
