The standard anionic surfactant method has several drawbacks:

*Multiple handling steps are time consuming and complicated.

*Large volumes of extraction solvents create a safety and environmental risk.

*The combination of lengthy handling time, glassware maintenance, and solvent disposal adds up to significant costs per test.

A standardised cuvette-based extraction and photometric measurement system overcomes all these disadvantages to provide accurate, reproducible results.

• Easy to use
• Safe to handle
• Cost saving
• Providing accurate and reproducible results
• Good phase separation even in samples with high organic load
