Description

General description

This polystyrene-based microparticle (size: 15 μm) size standard is ideal for profiling particle size distribution (PSD) of test samples.

Application

Used to standardize and monitor particle size analyzers and surface scanning instruments.
Also used to:

• standardize flow measurements of pumps used in lab-on-a-chip and point of care devices
• characterize counting accuracy and sizing measurements of impedance microfluidic chip
• optimize time-of-flight secondary ion mass spectrometry (ToF-SIMS) sample preparation based on size-dependent analysis

• Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Features and Benefits

• suitable for routine instrument calibration checks, testing and corrections
• available in 5 mL and 10 mL pack sizes as neat samples

Analysis Note

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
