Sample Holders for Imaging Intact Particles with the Scanning Force Microscope

We have fabricated and tested sample holders for scanning force microscopy (SFM) imaging of individual, intact particles in the range of 70–500 micrometers in diameter. The sample holders keep particles rigidly in place at the end of a micropipet during scanning (sample stage is vibrated by the piezo tube) through the use of flexible tubing connected to a simple laboratory aspirator. This design is shown to permit high resolution imaging of intact polymer adsorbent particles. The sample holders were tested by imaging adsorbent particles with the trade designations of Amberlite XAD-4, XAD-71, XE-348 and IRA-900 (Rohm & Haas Co., Springhouse PA). Polymer adsorbents were imaged in either the dry or hydrated state without immersing the SFM probe in solution.
