Grade 72 Activated Carbon Air Filter, 47mm Circle (100 pcs) SKU: 1872-047

Whatman Grade 72 Activated Carbon Air Filter - 1872-047

Air monitoring programs targeting both particulate matter and volatile organic compounds need a dual-function collection medium that eliminates separate sorbent tubes from the sampling train. Activated carbon impregnated into a borosilicate glass microfiber matrix adsorbs gas-phase organics while the fiber depth structure captures airborne particulates. Controlled manufacturing delivers the documented basis weight and carbon loading that reproducible air sampling methods require for comparable results across collection periods.

Key Material Characteristics

• Activated carbon layer adsorbs volatile and semi-volatile organic compounds directly from the sampled air stream during particulate collection.
• Borosilicate glass microfiber depth structure provides high particle loading capacity for extended-duration air sampling without premature flow restriction
• Nominal basis weight of 195 g/m² reflects the combined glass fiber density and carbon loading that determines collection capacity and flow characteristics.
• Dual-function filter design consolidates particulate capture and organic vapor adsorption into a single collection stage, simplifying sampling train configuration.
• Standard 47mm disc format fits conventional air sampling cassettes and filter holders used in occupational and environmental monitoring programs.

If your air monitoring program requires simultaneous particulate and organic vapor collection, the dual-function specifications above confirm this filter addresses both requirements. Combined particulate capture and vapor adsorption in a single disc simplifies your sampling train assembly and reduces the consumable complexity your field programs manage. Secure your air quality data with a Whatman collection medium engineered for the dual-phase monitoring demands of modern environmental and occupational programs.
