Thumbnail Filmstrip of 34mm Slotted Quartz Fiber Filters, 6-Slot, 100/pk for TE-298 Marple Impactor Images
The TE-290-QZ delivers precision-slotted quartz fiber filters specifically engineered for TE-298 Marple personal cascade impactors. These 34mm diameter filters feature six precisely positioned radial slots that align with the impactor's collection stages for accurate aerodynamic particle size distribution analysis.
High-Purity Quartz Construction
Made of very pure quartz fibers with no binders and glass fibers, these filters resist reaction with acidic gases that can cause false readings in glass fiber alternatives. The pure quartz composition prevents the filters from reacting with acidic gases, unlike glass fiber filters that can react and cause false readings. Quartz fiber filters have very low trace metal content and can withstand up to 1832°F (1000°C).
Cascade Impactor Compatibility
These slotted filters serve as the final collection stage in Series 290 Marple Style Personal Cascade Impactors operated at a flow rate of 2 LPM. After the last impactor stage, remaining fine particles are collected on the built-in 34mm filter. The six-slot design matches the particle cut-points for this series of impactors range from 21 to 0.5 microns.
- Diameter: 34mm
- Configuration: 6 radial slots
- Package: 100 filters per pack
- Temperature Rating: Up to 1000°C
- Material: Pure quartz fiber, binder-free
Applications
Essential for personal exposure monitoring using Marple cascade impactors in workplace health and safety assessments. Quartz fiber filters are used for air sampling in acidic gases(except HF), stacks, flues and aerosols, particularly at high temperatures and in PM-10 testing. Personal Cascade Impactor is a precision cascade impactor worn by personnel to provide complete and accurate aerodynamic particle size distributions of the particulate in their environment.
Handling and Storage
Pre-weigh filters before installation in the impactor for gravimetric analysis. Prior to sampling, collection substrates and the back-up filter are weighed and placed in the impactor. The filters also exhibit good weight and form stability, ensuring reliable mass measurements for particle quantification.
