Particle Deposition Systems

Reliable particle deposition is essential for high-quality microscopy and chemical analysis. Particle deposition systems enable researchers to deliver aerosols to substrates in a controlled, repeatable manner, producing samples that support confident interpretation. Whether the goal is a sparse distribution for single-particle analysis or uniform loading for averaged measurements, these systems provide the precision and flexibility needed in modern labs.

Key features:

• Method flexibility: Support electrostatic precipitation, inertial impaction, or flow-directed deposition to match particle size and material properties.
• Precise control: Adjust flow rate, deposition time, and, where applicable, electric field strength to tune areal density and spot morphology.
• Substrate compatibility: Prepare TEM grids, filters, wafers, coupons, and functional surfaces used in materials and life-science research.
• Integration: Connect upstream to classifiers and sizers (e.g., SMPS) or generators to produce size-selected, compositionally uniform samples.

Common applications:

• Electron microscopy sample preparation, including nanomaterial and catalyst studies.
• Spectroscopy and mass spectrometry where controlled loading aids quantitation.
• Filter media evaluation and calibration routines.
• Surface functionalization and materials development research.
• Toxicology research where reproducible exposures support dose-response studies.

Implementation guidance:

• Define target particle size distribution and desired areal density before selecting the method.
• Validate deposition uniformity with imaging or optical methods and refine parameters accordingly.
• Use consistent substrates and conditioning to help minimize variability.
• Document recipes and instrument parameters to support cross-team reproducibility and publication.

Particle deposition systems help teams translate aerosol streams into high-quality samples, reducing rework, speeding analysis, and strengthening the link between particle characterization and downstream measurement techniques.
