Restek Antifoam Agent for Purge & Trap Samples, Neat, 1 mL/vial

In purge-and-trap GC, foam may form as the purge gas passes through a sample. If this occurs, the foam can contaminate the analytical trap and possibly the GC column. To prevent this, our silica-containing antifoam agent can be used to effectively control foam over a wide pH range. See our instruction sheet for details on proper use, including the preparation and analysis of an antifoam blank.
