产品说明

一般描述

Monodisperse polystyrene based micro particles (size: 20.0 μm) are a particle size standard, designed for identifying the particle size distribution (PSD) profile of test samples.

应用

Fit for use in equipment particle size calibration.
Also used to:

standardize methods of size-dependent chromatographic separations.
validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements.
determine the impact of polystyrene microplastic exposure on feeding capacity of marine copepod Calanus helgolandicus.
produce monolayers in the synthesis of 2D nanomaterials coated micromotors

特点和优势

suitable for routine instrument calibration checks, testing and corrections
available in 5 mL pack size as a neat sample

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。
