产品说明

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

采用 NIST-BCR-粒度标准品进行设备校准。
