SST Collection Plates for Non-Viable Andersen Cascade Impactor (Set of 9) SKU: TE-20-702A

The TE-20-702A stainless steel collection plate set provides precision particle collection surfaces for TE-20-800 series non-viable Andersen cascade impactors. These stainless steel plates are designed for durability and reliable particle impingement, enabling accurate aerodynamic particle size distribution analysis for ambient air monitoring and source testing applications.

The collection plates serve as the impaction surface where particles are deposited based on their aerodynamic diameter. As air passes through each stage of the cascade impactor, larger particles impact on the collection plate surface while smaller particles remain in the airstream to cascade through successively smaller stages. The stainless steel plates are positioned with the curved lip down to provide a raised, smooth surface for optimal particle impingement.

Set Configuration

• Total plates: 9 precision-machined stainless steel plates
• Open-center plates: 2 plates with centers removed for airflow passage
• Solid collection plates: 7 plates for particle capture
• Material: Corrosion-resistant stainless steel construction

Compatibility

These collection plates are specifically designed for use with TE-20-800 series eight-stage non-viable Andersen cascade impactors. Each plate rests on three raised metal seats to prevent movement during operation, with metal pins extending from each orifice stage to hold the plates securely in place.

Applications

Compatible with particle size separation from >10µm to <0.4µm at the standard 28.3 ALPM flow rate. Stainless steel plates are commonly used for gravimetric analysis and applications where durability and chemical resistance are required. Suitable for ambient air quality monitoring, industrial hygiene assessments, and research applications requiring precise particle size distribution data.

Note: Plates should be installed with the curved lip facing down to maintain proper jet-to-collection surface spacing. Regular inspection for mechanical wear or contamination is recommended to ensure measurement accuracy.
