描述

一般說明

Ideal for determining particle size distribution (PSD) profile of test samples.
The accurate diameter of 3 μm is determined by methods described by the National Institute of Standards and Technology (NIST, USA), such as:

• Transmission electron microscopy
• Scanning electron microscopy
• Optical microscopy
• COULTER COUNTER particle size analyzer with HDF system.

The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692).

應用

Used to calibrate equipment particle size.
Also used as a test sample:

• in blood flow measurement experiments
• to calibrate resonant photothermal spectroscopy equipment

特點和優勢

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