一般描述

Monodisperse polystyrene based micro particles (size: 200 μm) are a size standard, ideal for profiling particle size distribution (PSD) of a particle system.
The particle diameter of 200 μm is characterized using Olympus optical microscope. The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692).

应用

Used to calibrate and monitor the performance of particle size analyzers.

特点和优势

• suitable for routine instrument calibration checks, testing and corrections
• available in 5 mL and 10 mL pack sizes as neat samples

分析说明

对于每个批次，测定粒度和标准偏差的精确值的准确度为 0.001 μm。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
• 光学显微镜术
• 配备 MDF 系统的 Coulter^?计数器
