The pharmaceutical industry operates under stringent production compliance and safety standards, mandating strict oxygen control for core processes including sterile preparation manufacturing, API synthesis and inert gas packaging. Abnormal oxygen fluctuations cause pharmaceutical oxidation deterioration, excessive microbial contamination and undesired side reactions, severely impairing drug quality and shelf life. High-risk pharmaceutical production environments impose rigorous requirements on gas detection equipment in terms of precision, stability and explosion-proof compliance.
Conventional oxygen testing instruments suffer from low accuracy, slow response, weak anti-interference performance and frequent calibration requirements, failing to meet GMP standardized continuous pharmaceutical production demands. Developed with mature TDLAS technology, Chengdu HonryTech HT-FX760 laser oxygen analyzer integrates high precision, rapid response, powerful anti-interference capacity, infrequent calibration and full explosion-proof compliance to satisfy oxygen monitoring demands across pharmaceutical processes, sealed chambers and inert gas purging applications, delivering stable support for pharmaceutical manufacturers’ quality control, safe production and regulatory compliance.

【Project Background】: The Core Pain Points of Oxygen Content Monitoring in the Pharmaceutical Industry
Multiple large and medium-sized domestic pharmaceutical manufacturers covering sterile preparations, API and pharmaceutical excipient production have long encountered persistent oxygen monitoring challenges categorized into four core pain points:
1. Insufficient testing precision hinders quality compliance: Processes such as drug synthesis, lyophilization and sterile filling require tightly controlled low-oxygen atmospheres. Low resolution of traditional equipment prevents accurate capture of minor oxygen fluctuations, leading to batch oxidation failures and unstable product qualification rates.
2. Poor anti-interference performance generates large data deviations: Water vapor and trace volatile organic solvent vapors present in pharmaceutical production environments cause cross-interference for conventional detectors, resulting in drifting, distorted monitoring data that fail to satisfy GMP traceability standards.
3. Delayed response and cumbersome maintenance reduce production efficiency: Slow response of traditional analyzers cannot reflect instantaneous gas fluctuations in real time, delaying timely adjustment of production parameters. Frequent calibration and consumable replacement drive up maintenance costs and interrupt continuous production during calibration shutdowns.
4. Insufficient explosion-proof compliance creates safety hazards: API synthesis and organic solvent storage workshops are classified as high-risk explosion-proof zones. Standard detection equipment lacks adequate explosion-proof ratings for compliant deployment in such hazardous areas, posing significant occupational safety risks.

【Solution】: The HT-FX760 laser oxygen analyzer is precisely designed to meet the requirements of the pharmaceutical industry.
We customized and deployed HT-FX760 explosion-proof laser oxygen analyzers for pharmaceutical clients to meet multi-scenario, ultra-rigorous monitoring requirements.
