FAQ

  • Q What is the measurement range of the oxygen analyzer in the glove box?

    A The oxygen analyzer in the glove box is a key device used to monitor the oxygen concentration inside the glove box, with a measurement range typically from 0 to 1000 ppm. Most of these analyzers use zirconia sensors, which have a longer lifespan and can operate stably in high oxygen environments. Compared to traditional fuel cell (electrochemical cell) sensors, which may be damaged in high oxygen environments and have a shorter lifespan.
  • Q Why is the proportion of hydrogen in the regenerated gas of the glove box 5-10%?

    A In the regeneration process of the glove box, the role of hydrogen is to reduce the copper catalyst, restore its activity, and effectively remove oxygen from the glove box. Hydrogen is mixed with working gases such as nitrogen, argon, or helium, with the proportion of hydrogen controlled at 5-10%, because this ratio can ensure sufficient reducing ability and avoid safety risks caused by high hydrogen concentration. In addition, this ratio can ensure maximum chemical reaction efficiency during the regeneration process while reducing unnecessary energy consumption.
  • Q How is the regeneration operation of the glove box automatically controlled?

    A The regeneration operation of glove boxes is usually automatically controlled by PLC (Programmable Logic Controller) to ensure the effective recovery of water and oxygen removal materials. The PLC system will automatically adjust the gas flow rate, temperature, and time during the regeneration process according to preset programs and parameters, thereby achieving precise control. During the glove box regeneration process, the PLC will control the mixing ratio of working gas and hydrogen gas to ensure that the hydrogen gas is within the range of 5-10%, in order to optimize the regeneration effect.
  • Q What should be noted when replacing the vacuum pump oil in the glove box?

    A When replacing the vacuum pump oil in the glove box, it is necessary to ensure that the used oil in the pump body is completely drained and the pump chamber is cleaned to avoid contaminating the new oil. During the process of replacing the pump oil, use specialized refueling tools and avoid contact with other oils or solvents to maintain the purity of the vacuum pump oil. Proper maintenance and timely replacement of vacuum pump oil are crucial for maintaining the performance of the vacuum pump.
  • Q How often does the vacuum pump oil in the glove box change?

    A The oil replacement cycle of the vacuum pump in the glove box usually depends on the working conditions and frequency of use of the pump. In general, it is recommended to replace the vacuum pump oil according to the time provided by the glove box supplier to ensure efficient operation and extend the service life of the pump. If the vacuum pump oil turns black, yellow, or brown during use, it is a clear sign of deteriorating oil quality and should be replaced immediately to avoid affecting pump performance and causing equipment damage. In addition, if the odor of the pump oil changes, or if the liquid level of the pump oil rises or falls abnormally during use, it is also a signal that the oil needs to be replaced.
  • Q What are the advantages of the phosphorus pentoxide (P ₂ O ₅) sensor used in the glove box water analyzer?

    A The advantages of the phosphorus pentoxide (P ₂ O ₅) sensor used in the glove box water analyzer include high measurement sensitivity, suitability for measuring very small amounts of moisture, and the ability to measure corrosive gases. This type of sensor can also be regenerated regularly to make it reusable and maintain its accuracy. When used in high humidity environments, the lifespan of the pentoxide phosphorus coating may be shortened, so the interval time for regenerating the water analyzer needs to be determined according to the situation.
  • Q What is the measurement method for moisture content using the pentoxide (P ₂ O ₅) sensor used in the glove box water analyzer?

    A The working principle of a phosphorus pentoxide (P ₂ O ₅) sensor is based on electrolysis, which determines the moisture content in a gas sample through the sensor's current. The sensor consists of two platinum electrodes and a phosphorus pentoxide coating surrounding a quartz tube. When gas flows through the sensor, the moisture in it is absorbed by the phosphorus pentoxide coating and electrolyzed into hydrogen and oxygen at the electrode. The current generated during this process is directly proportional to the concentration of moisture in the gas, so the moisture content can be determined by measuring the current.
  • Q Does the water probe of Mikrouna glove box have corrosion resistance?

    A The water probe of Mikrouna glove box has corrosion resistance, which means it can be used for a long time in environments containing different chemical components without corrosion, ensuring the stability and reliability of measurement.
