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.

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

Download your certificate at https://www.sigmaaldrich.com/US/en/documents-search to view certified values, including uncertainty and expiry date.

Application

Potassium chloride solution is a certified reference material intended for use in aqueous solution as a calibration standard for the measurement of the conductivity cell constant or as a control sample.

Analysis Note

Electrical conductivity (25 °C): 1.39 - 1.43 mS/cm

Questions

1–2 of 2 Questions  

  1. How many times can the same packet/pouch (30ml) be used for calibration? 1.01553 Supelco Potassium chloride solution Certified Reference Material

    1 answer

    1. There is no specific limit on the number of times the same packet or pouch (30 ml) can be used for calibration, provided that the product is stored under proper conditions. To ensure the integrity and accuracy of the solution, follow the recommended storage guidelines outlined in Section 7.2 of the Safety Data Sheet (SDS).

      Helpful?

  2. Do we have to dilute the 30 ml liquid to get the desired concentration or use it directly to calibrate the Electrical conductivity meter?

    1 answer

    1. No dilution is required. The 30 mL size is packaged as a sachet or pouch ready for use.
