Beschreibung

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

Für jede Charge werden die exakte Partikelgrösse und die Standardabweichung mit einer Genauigkeit von 0.01 μm unter Verwendung eines Coulter Multisizers bestimmt.
