SRM 1993_cert
SRM 1993_SDS
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.
