Application of trace oxygen anayzer in glove box

I. Application of glove box

       Glove box is a general working platform to provide a very high purity inert gas environment, the inert gas concentration in this working platform can reach a very high level, some very sensitive to water or oxygen materials research, process or experiment can be achieved in the glove box.

       Glove box has been increasingly used in scientific experiments, new materials research and development, biomedical, chemical, lithium batteries, solar cells, nuclear materials and nuclear industry, new lighting, special welding, vacuum coating and other industries and fields. As a universal platform, the glove box can provide working conditions for experiments or production that need to be realized in high purity inert gas protection, low water and oxygen content, or dust-free and sterile environments.

II. Application of trace oxygen analyzer products in the lithium industry glove box

       1. Install the trace oxygen analyzer in the glove box: it is used to monitor the oxygen content in the box, and the current content can be displayed on the touch screen.

       2. The  trace oxygen analyzer can be interlocked with the circulation fan and purifier in the glove box to continuously remove oxygen when the oxygen content is high to maintain the test or production conditions.

       3. Trace oxygen analyzer in the glove box purification system for regeneration, monitoring the oxygen content in the box, purification 24 hours in the box should be less than 1PPM oxygen content, such as high content can be suspected that the glove box is not sealed or there are other problems.

       4. According to the site process requirements, you can set the upper and lower alarm points of the oxygen content of the gas to be measured.

       5. Can be used to monitor the oxygen content rise in the process of discharging and feeding caused by switching the transition chamber.

III. Current market commonly used Trace oxygen analyzer and principle

1. Electrochemical principle (such as MZD, Teledyne, GE, AII/ADV).

High measurement accuracy, stable operation, low price, short battery life, frequent calibration with standard gas, high maintenance cost. It can overcome the interference of acid gas, but it is not resistant to long-term corrosion of hydrogen fluoride/hydrofluoric acid.

2. Zirconia principle (such as MZD, MBRAUN).

High measurement accuracy, stable operation, higher price, long service life of sensor, maintenance-free. It can overcome the interference of acid gas, but cannot be used in reducing gas occasions.

2.1 The electrode is coated with a special protective layer, which greatly enhances the corrosion resistance of the electrode can overcome the interference of acid gases and is resistant to hydrogen fluoride/hydrofluoric acid corrosion.

2.2 The core component of zirconia oxygen analyzer, zirconia element, adopts unique formula and advanced molding process, which makes its measurement accuracy and working life.

2.3 The surface of the zirconia electrode has been treated with a special process, which has greatly improved the measurement sensitivity and accuracy.

2.4 The zirconia probe adopts unique sealing technology, which has the characteristics of anti-dust plugging, anti-scouring and sensitive response.

IV. MZD trace Oxygen analyzer (Zirconia Principle) Products

1. Zirconia sensor technology.

2. Range 0-1000PPM can be set by yourself.

3. High precision.

4. Long sensor life.

5. Calibration-free and maintenance-free.

6. Fast response time.

7. Low interference of sample gas flow rate.
