Description

General description

This ready-to-use certified reference material (CRM) is produced and qualified following ISO 17034 and ISO/IEC 17025. It is manufactured gravimetrically with traceability to SI and higher order standards from National Institute of Standards and Technology (NIST). Its certified value is based on purity determination by mass balance and gravimetrically prepared value. It is delivered in a 500 mL HDPE bottle.

All information regarding metrological traceability, uncertainty, homogeneity and stability is documented in the certificate of analysis (CoA).

Application

Suitable for use in calibration of instruments for conductivity measurements.

Other Notes

Values of analytes vary lot to lot. Some lots may not contain all analytes.
