发明名称 Detection of defects in protective barriers
摘要 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.
