Solutions For TOC Analysis

Total Organic Carbon (TOC) Analysis Solutions for Detecting Organic Contamination in Water

Dissolved organic carbon is oxidised by sodium persulphate reagent and CO2 produced is measured by spectrophotometry. Many other reagents in solution are used: acids, bases ...depending on type of water analysed. The most common reagents can be supplied by VWR, for example:

• Sodium hydroxide 1.2 N solution
• Sulphuric acid 1.8 N solution
• Sodium persulphate solutions, at various concentrations
• Phosphoric acid 10% solution
• Phosphoric acid 25% solution

Many other solutions are possible - please enquire.
