• Activated charcoal for extraction
of nitrosamines and dioxane in
drinking water.
• Batch tested to ensure low
background and consistent recoveries.
• High-quality polypropylene tubes
and frits to minimize interference.
• Specially treated charcoal and frits
to minimize fines that result from
inconsistent recoveries.
