Product details
High purity hydrogen gas generator for gas chromatography
hydrogen generatorOverview and working principle:
high-purityhydrogen generatorIt mainly consists of an electrolysis system, a pressure control system, a purification system, and a display system. Electrolytic hydrogen adopts advanced membrane separation technology, uses high-quality stainless steel tank body, and a pressure control system composed of infrared photoelectric feedback device and stable voltage and current switch power supply. The amount of hydrogen generated can be automatically adjusted according to the output needs, ensuring the stability of output flow rate and pressure. It can provide gas or carrier gas for various types of chromatographs at home and abroad. The product is widely used in chemical, environmental protection, petroleum, papermaking, power, food, pharmaceutical, scientific research and other fields.

hydrogen generatorTechnical features:
Fully automatic type, flow LED display, automatic tracking, simple operation, easy maintenance;
The gas and liquid paths are relatively independent and well isolated. The gas-liquid separation device can ensure gas-liquid separation and automatically return the liquid to the electrolytic cell under pressure, completely solving the problem of liquid return;
Double electrolytic cells are connected in series and equipped with microporous electrodes, resulting in high electrolysis efficiency and long service life Stable performance during use, stable pressure and flow output, and no degradation in purity;
Equipped with two-stage overvoltage protection, there is less residual gas when stopped, ensuring safe use Power outage has the function of automatically closing the air circuit.

When using a high-purity hydrogen generator, the specific steps are as follows:
1. Open the packaging box, take out the high-purity hydrogen generator, check the appearance of the instrument, and verify the packing list.
2. Add electrolyte: Dilute and dissolve analytical pure potassium hydroxide with distilled water, cool it down, and inject it into the liquid tank through the inlet with a funnel. Then add distilled water to the liquid level near the mark.
3. Tighten the sealing cap on the hydrogen output port on the rear panel of the high-purity hydrogen generator.
4. Connect the power supply and check the grounding terminal of the instrument power cord to ensure reliable grounding.
5. Start the high-purity hydrogen generator and observe the flow rate display (note: there may be fluctuations in the digital display of hydrogen production at the beginning of startup, which is a normal phenomenon).
6. The pressure gradually increases, and when the pressure reaches the set value, the digital display returns to zero and shows "000", indicating that the instrument is normal and no longer producing hydrogen.
7. After starting up normally, first turn off the machine, then remove the sealing cap on the hydrogen outlet, connect it to the instrument through a pipeline, and ensure that the sealing joint does not leak. Then start the instrument and wait for the pressure to reach the set pressure before use.
There are some things to note in these steps, such as placing the high-purity hydrogen generator on the workbench for easy observation and operation, not allowing the high-purity hydrogen generator to run for a long time (more than 5 minutes) under zero pressure, regularly observing the discoloration of the drying tube, and timely replacing the discoloration silicone gel, etc. Don't underestimate these details, doing them well can greatly improve work efficiency.
