摘要： Leaks from a hollow fiber membrane module comprising a housing having one or more hollow fiber bundles positioned therein with at least one end of each bundle being sealed by a cementing layer includes the step of applying a pressurized gas to the external surfaces of the hollow fibers. The gas which is used must have a refractive index different from the refractive index of the ambient atmosphere. The atmospheric volume adjacent the sealed end of the module is optically monitored for refraction patterns caused by gas leaking through the sealed end into the volume. The optical system includes a light source and components for directing light from the source along an optical path including the monitored volume. Light which is passed through the monitored volume is directed to an optical display where the refraction patterns of the leaking gas will be visible. The method and apparatus permit leaks to be located without the use of liquids.
