描述

一般說明

Monodisperse polystyrene based micro particles (size: 12.0 μm) are a particle size standard, designed to identify the particle size distribution (PSD) profile of test samples.

應用

Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
Also used:

• in acoustic traps to study the effect of particle detection on trapping performance of lab on a chip systems
• as a reference of known dimensions to characterize real-time imaging systems
• as a calibration standard to validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements.

特點和優勢

• suitable for routine instrument calibration checks, testing 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。
