Antifoam Agent for Purge & Trap Samples
Foam generated as purge gas passes through a sample can enter the
analytical trap, and possibly the GC column. Our silica-containing
antifoam agent is effective over a wide pH range, and will not conflict
with chromatography of target analytes.
Neat, 1mL/ampul

• 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 in
inconsistent recoveries.
