Application
SRM 1993 is intended primarily to evaluate the performance of instruments and techniques used to measure the zeta potential and electrophoretic mobility, particularly in electroacoustic methods requiring a high mass fraction and calibration.
It can also be used to calibrate electroacoustic instruments requiring relatively high mass fraction.

Caratteristiche e vantaggi

• The NISTcertified values are determined using electrophoretic light scattering and valuesare traceable to the International System of Units (SI).
• Provided with non-certifiedvalues ideal for use in method harmonization, methoddevelopment, and process control.
• Expiration Certification, instructions for handling, storage,and uses are provided on the NIST certificate.
