Many fans have asked: What testing items do oxygen analyzers for laboratory centrifuges include? Today, we'll discuss this topic to help everyone quickly understand the knowledge related to online monitoring of oxygen content in centrifuges.
In various chemical, materials, and pharmaceutical laboratories, centrifuges are used in many experimental scenarios, and precise online gas analysis equipment is required to conduct tests, collect, and analyze data. Some centrifuge experiments involve inert gas protection and volatile organic solvents, making the experimental environment complex. If the equipment is not properly selected or operated incorrectly, it can not only interfere with the instrument's operation and damage the stability of the equipment, causing sensor wear and data distortion; in severe cases, abnormal oxygen levels inside the chamber can pose a risk of combustion and explosion, directly threatening the health of laboratory personnel and the safety of laboratory property.
Equipping a centrifuge station with an oxygen content analyzer is an important means of laboratory safety protection, with the core being the ability to achieve 24-hour continuous real-time online monitoring of oxygen concentration inside the centrifuge. The instrument continuously collects sample gas from the centrifuge chamber and provides real-time feedback on the oxygen concentration values inside. Once the oxygen concentration exceeds the safety threshold set for the experiment, the system immediately triggers audible and visual alarms, promptly reminding laboratory personnel to take measures such as filling with inert gas and shutting down for inspection, thereby avoiding safety accidents like combustion and explosion and providing a solid safety barrier for laboratory personnel.
The application of oxygen content analyzers is not limited to laboratory centrifuges; they are widely used in many industries such as pharmaceutical synthesis, fine chemicals, agricultural gas cultivation, and heat treatment protective gases. The gas composition, temperature and humidity, and impurity content vary greatly in different on-site conditions, so the instrument supports customized configurations based on actual on-site conditions to meet the monitoring needs of different processes.
Taking Xi'an Runlai Instrument Co., Ltd.'s RL-E100Ex explosion-proof oxygen analysis system as an example, the entire system consists of a main analyzer, a sampling unit, a sample gas pretreatment unit, and an alarm output module. The entire set of equipment comes with a complete pretreatment system, including core components such as sampling probes, gas washing tanks, gas-liquid separators, gas source processors, and condensers.
Sample gas drawn from the site often contains various interfering impurities such as organic solvent vapors, organic substances, water vapor, and dust. Direct entry into the analyzer can corrode sensors, causing measurement errors or even equipment damage. This system can purify the collected sample gas through various treatment methods such as PTFE corrosion-resistant pipelines, alkaline washing, alcohol washing, and multi-stage adsorption, effectively removing organic solvents, organic substances, moisture, and trace impurities from the on-site gas, and processing the sample gas from complex conditions to standard testing conditions of dryness, stable pressure, and constant flow.
After pretreatment, the clean sample gas is then sent to the oxygen analysis main unit for testing. On one hand, this ensures accurate and reliable test data and reduces measurement errors caused by environmental interference; on the other hand, it can reduce the erosion of corrosive media on sensors and internal components, effectively extending the overall service life of the instrument and sensors and reducing subsequent maintenance costs, making it very suitable for long-term continuous operation in complex conditions such as laboratory centrifuges containing organic solvents.
