This includes:\n <ul>\n <li><strong>Airflow Monitoring:<\/strong> Mandatory installation of air circulation devices and anemometers in pre-conditioning, sterilization, and aeration chambers.<\/li>\n <li><strong>Direct Humidity:<\/strong> Real-time measurement during the treatment phase.<\/li>\n <li><strong>EO Concentration:<\/strong> Direct measurement at all required intervals during exposure.<\/li>\n <li><strong>Dual Temperature Points:<\/strong> At least two independent sensor locations representing the chamber state.<\/li>\n <\/ul>\n <\/div>\n <\/div>\n\n <h3>1.1 Sensor Technologies & Calibration<\/h3>\n <div class=\"clause-card\">\n <span class=\"clause-id\">Humidity Measurement<\/span>\n <div class=\"clause-content\">\n Measured via <strong>Capacitance Film<\/strong> (Relative Humidity) or <strong>Spectroscopy<\/strong> (Absolute Humidity). Sensors must be calibrated using saturated salt solutions and protected from EO-induced drift through frequent validation or thermal isolation.\n <\/div>\n <\/div>\n\n <img decoding=\"async\" src=\"https:\/\/zjbocon.com\/wp-content\/uploads\/2026\/03\/eto-sterilizer-25.webp\" alt=\"EO Monitoring Sensors\" class=\"article-img\">\n <p class=\"img-caption\">Integrated Humidity and EO Concentration Monitoring Systems.<\/p>\n\n <div class=\"clause-card\">\n <span class=\"clause-id\">EO Concentration (Spectroscopy & GC)<\/span>\n <div class=\"clause-content\">\n Accuracy and precision must be documented. <strong>IR Spectroscopy<\/strong> (Infrared absorption) or <strong>Gas Chromatography (GC)<\/strong> are the standard methods. External sampling lines must utilize <strong>Heat Tracing<\/strong> to prevent condensation.\n <\/div>\n <\/div>\n\n <h2>2. Sterile Release of Products (Chapter 11)<\/h2>\n \n <div class=\"clause-card\">\n <span class=\"clause-id\">2.1 Criteria for Parametric Release<\/span>\n <div class=\"clause-content\">\n Routine sterile release is based solely on <strong>physical processing parameters<\/strong> meeting established specifications during validation. Unlike traditional methods, it does not rely on Biological Indicator (BI) testing results. A documented review by authorized personnel is mandatory.\n <\/div>\n <\/div>\n\n <img decoding=\"async\" src=\"https:\/\/zjbocon.com\/wp-content\/uploads\/2026\/03\/eto-sterilizer-20.webp\" alt=\"Data Recording and Control System\" class=\"article-img\">\n <p class=\"img-caption\">Documented Review and Physical Parameter Control for Batch Release.<\/p>\n\n <div class=\"clause-card\">\n <span class=\"clause-id\">2.2 Sensor Integrity and Accuracy<\/span>\n <div class=\"clause-content\">\n If control or monitoring sensors fail to meet specifications, or if an investigation cannot confirm the accuracy of chamber readings, the <strong>load must be considered non-compliant<\/strong>.\n <\/div>\n <\/div>\n\n <h2>3. Deviations and Investigations<\/h2>\n\n <div class=\"clause-card\">\n <span class=\"clause-id\">3.1 Handling Out-of-Specification (OOS) Data<\/span>\n <div class=\"clause-content\">\n When parameters exceed limits, an investigation must determine the root cause. Products must be quarantined until a safety assessment is completed.\n <div class=\"note-box\">\n <strong>Load Characteristics:<\/strong> If EO or humidity data is OOS while controls are normal, evaluate the <strong>loading pattern<\/strong>. Differences in absorption compared to the initial PQ load may be the cause.\n <\/div>\n <\/div>\n <\/div>\n\n <div class=\"clause-card\">\n <span class=\"clause-id\">3.2 Corrective Actions and Re-release<\/span>\n <div class=\"clause-content\">\n If a sensor fails, the process may temporarily revert to <strong>Biological Indicator release<\/strong> during repairs. Parametric release can be resumed only after equipment repair and re-calibration.\n <\/div>\n <\/div>\n\n <img decoding=\"async\" src=\"https:\/\/zjbocon.com\/wp-content\/uploads\/2026\/03\/eto-sterilizer-17.webp\" alt=\"Maintenance and Calibration\" class=\"article-img\">\n <p class=\"img-caption\">Calibration and Maintenance Ensuring Sensor Precision for Continuous Parametric Release.<\/p>\n\n <div class=\"clause-card\">\n <div class=\"clause-content\">\n <strong>Critical Note:<\/strong> A process that fails parametric release specifications <strong>should not<\/strong> be released based on successful BI results.
