Foamtec’s PolyCHECK FM Identification Process: A Superior Alternative to SEM Stubs

by | Nov 20, 2023

In the meticulous world of cleanroom operations, the identification and analysis of foreign material (FM) are paramount. Traditionally, Scanning Electron Microscope (SEM) Stubs have been the go-to for particle detection. However, Foamtec’s innovative PolyCHECK FM Identification Process is changing the game, offering a multitude of advantages that make it a superior choice for cleanroom professionals.

Foamtec’s PolyCHECK FM (Foreign Material) Identification Process presents several advantages over SEM Stubs. The key benefits include:

  1. Speed and Surface Area: PolyCHECK wipes and swabs can collect samples from both large and small surfaces very quickly, which is much more efficient than using SEM Stubs​​.
  2. Operational Continuity: The PolyCHECK process does not require facilities or workstations to shut down during the sample collection, meaning that it can be integrated into the workflow without causing operational delays​​.
  3. Contamination Analysis and Resolution: Not only does the PolyCHECK process provide detailed contamination analysis, but it also assists in providing solutions for foreign material removal​​.
  4. Integration with SEM Analysis: While the swabs themselves eliminate the need to directly contact SEM stubs with critical surfaces, they are still ideal when used in conjunction with SEM analysis, allowing for a comprehensive approach to particle detection and analysis​​​​.
  5. Enhanced Particle Retention: PolyCHECK material is designed to attract and hold particle contamination effectively, making it easier to transfer samples to SEM stubs for further analysis using techniques like SEM/EDX (X-ray dispersion) and FTIR (Fourier Transfer Infrared Spectroscopy)​​.

These features make Foamtec’s PolyCHECK FM Identification Process a versatile and non-disruptive choice for cleanroom and critical surface cleanliness validation, particularly in environments where minimizing downtime and maintaining operational flow are crucial.
