TE-EPM2000 High Purity Glass Fiber Filters for TSP, 8" x 10" Numbered (100/box) SKU: TE-EPM2000

TE-EPM2000 High Purity Glass Fiber Filters for TSP, 8" x 10" Numbered (100/box)

The TE-EPM2000 glass fiber filters are designed for use in US EPA TSP ambient air monitoring applications. These 8" x 10" (203.2 x 254 mm) high purity glass fiber filters feature sequential numbering for sample tracking and chain-of-custody requirements. Each filter provides binderless borosilicate glass construction with 450 µm nominal thickness, ensuring reliable collection of total suspended particulate matter for regulatory compliance monitoring.

EPA Compliance and Applications

These filters meet the requirements of 40 CFR Part 50, Appendix B for total suspended particulate matter (TSP) measurement in ambient air for determining compliance with national ambient air quality standards. The filters are used in high volume air sampling equipment that collects atmospheric particulates and aerosols.

Sampler Compatibility

TE-EPM2000 filters are compatible with all Tisch Environmental high volume TSP samplers and other high-volume samplers including Andersen, Thermo, and GMW models for TSP collection. The standard 8" x 10" format ensures proper fit in filter holders and maintains sampling integrity throughout the collection period.

Material Properties

The 100% micro-fine borosilicate glass fiber construction provides exceptional chemical resistance and thermal stability. Glass fiber filters offer high flow rates, excellent chemical resistance, high thermal stability and are very pure - with no binder materials added during manufacturing. Glass fiber filters are comparatively insensitive to changes in relative humidity, making them ideal for ambient monitoring applications.

Sample Handling

Each filter is pre-numbered for sample identification and tracking. Following EPA protocol, filters must be weighed after moisture equilibration before and after use to determine net weight gain. Careful handling between presampling and postsampling weighings is necessary to avoid errors due to loss of fibers or particles. Store exposed filters properly folded to protect collected particulate matter.
