Abstract: The invention includes apparatus and method for detecting defects in various barrier materials including surgical gloves and food packaging. Voltage is applied across electrodes and a barrier material and the voltage measured and compared with voltage control measurements for the same barrier material without a defect. Sensitivity of measurements is increased by adjusting partial pressure across the barrier material which is subjected to the passage of an ionized gas detected by suitable instrumentation.
