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.
For more information, please refer to the SDS and COA.

Features and Benefits
- 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.
