一般說明

Monodisperse polystyrene based micro particles (size: 8.0 μm) are a particle size standard, ideal to determine the particle size distribution (PSD) of test samples.

應用

Intended for use in validation and monitoring of the performance of particle sizing instruments.
It′s also used to:
  • standardize methods of size-dependent chromatographic separations.
  • characterize electrical impedance spectroscopy (EIS) performance of microfluidic device by size measurement.

特點和優勢

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

分析報告

对于每个批次,测定粒度和标准偏差的精确值的准确度为 0.001μm。这些颗粒的粒度测定分别遵循美国国家标准与技术研究所 (NIST, USA) 和欧盟参考局 (BCR) 描述的程序,尤其是:
  • 透射电子显微镜(TEM)
  • 扫描电子显微镜
  • 光学显微镜
  • Coulter 计数器,带MDF系统
采用NIST-respectively BCR粒度标准物质进行设备校准。
