General description
Monodisperse polystyrene based micro particles (size: 3.0 μm) are a size standard, designed to identify the particle size distribution (PSD) profile of test samples.
Application
Used to validate and monitor the performance of particle sizing equipment.
Also used:
Also used:
- in acoustic traps to study the effect of non-contact retention of microparticles on trapping performance of lab on chip systems
- to synthesize microsphere-based interferometric optical probe called reflectophore
Features and Benefits
- suitable for routine instrument calibration checks and corrections
- available in 5 mL pack size as a neat sample
Analysis Note
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
