General description

Water standard oil is composed using transformer oil and its water content is measured by coulometric Karl Fischer titration. It is designed for applications requiring the measurement of water content in oil samples.

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

In our effort to be more sustainable, we′re going digital with COAs-download them directly from our website. Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

Application

It finds applications as a certified reference material (CRM) in checking the accuracy of coulometric Karl Fischer titrators as per ISO 9001 chapter 7.1.5 “Monitoring and measuring resources”.
