一般描述
Monodisperse polystyrene based micro particles (size: 0.5 μm) are a particle size standard, designed to profile the particle size distribution (PSD) of test samples.
应用
Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
Monodisperse polystyrene latex particles are also used to find the PSD of colloidal dispersions.
Monodisperse polystyrene latex particles are also used to find the PSD of colloidal dispersions.
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 0.001μm。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
