Powder Generators

Dry powder generation is central to research areas where particle composition and morphology matter. TSI powder generators disperse materials ranging from fragile actives to cohesive industrial powders, helping teams achieve stable aerosol concentrations and reproducible distributions for rigorous studies.

Applications:

• Inhalation toxicology and dose-exposure relationships
• Filter media and respirator testing with dry particulate challenges
• Material performance screening and environmental simulation
• Worker exposure assessment and control technology evaluation
• Device development for dry powder delivery systems

Technical Benefits:

• Consistent Mass Output: Meter powders with fine control to support precise dosing and time-weighted averages.
• Effective Deagglomeration: Mechanical dispersion mechanisms help reduce clumping for more representative aerosols.
• Broad Powder Compatibility: From pharmaceutical blends to metal oxides and carbonaceous materials.
• System Integration: Works with cascade impactors, OPCs, CPCs, and gravimetric samplers for comprehensive characterization.

Best Practices:

• Pre-condition powders to manage humidity effects and flow behavior.
• Validate aerosol properties with real-time instruments and filter samples.
• Document feed rates, dispersion settings, and environmental conditions for repeatability.
• Use appropriate safety and containment practices for hazardous materials.

Selection Considerations:

• Powder cohesiveness and particle size distribution
• Required concentration, flow rate, and runtime
• Desired degree of deagglomeration
• Downstream measurement and sampling methods

Outcome:
A reliable powder generator supports clear dose-response curves, robust filtration data, and faster iteration on material choices. TSI can help you select a system that aligns with your powder properties, target concentrations, and downstream analysis.
