General description

This certified reference material (CRM) is directly traceable to the corresponding primary reference material from the Physikalisch Technische Bundesanstalt (PTB), Germany. The electrolytic conductivity of this standard is determined using a conductivity meter from an accredited Merck calibration laboratory.

The details of expiry date, health & safety, storage & handling, and associated uncertainty are documented in the certificate of analysis.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

Application

Used as a calibration standard to measure electrolytic conductivity in aqueous solution, typically to determine conductivity cell constant or as a control sample.

Analysis Note

Electrical conductivity (25 °C): 110.0 - 112.0 mS/cm
