Dissolved oxygen describes the amount of oxygen molecules (O2) which are dissolved in a liquid phase under certain conditions. In this white paper, two different methods for the analysis of dissolved oxygen (DO), titration and direct measurement, are compared to help analysts determine which method is more suitable for their specific applications.
What will you learn:
- What is dissolved oxygen?
- How to determine the dissolved oxygen content in water
- Winkler titration (ISO 5813, EN 25813, ASTM D888, EN ISO 5815-1, ISO 5815-2)
- DO Measurement with electrochemical sensors (EN ISO 5814, ASTM D6764, EN ISO 5815-1, ISO 5815-2)
- Measurement using an optical sensor (ISO 17289)
