  • QUALITY CONTROL METHOD AND MICRO/NANO-CHANNELED DEVICES
    Publication number: 20110137596
    Abstract: Embodiments of the present invention comprise a quality control system and method for testing micro- or nano-channeled devices. The system and method can utilize a pressure-driven gas flow for the detection and quantification of structural defects. The test method and system are non-destructive and allow defects to be detected and classified quickly based on measured factors, such as mass flow rate for a given pressure differential.
