High purity hydrogen generatorBy using proton exchange membrane technology combined with drying and purification technology, the purity of hydrogen can reach 99.999% or even higher, meeting the gas or carrier gas supply needs of equipment such as gas chromatographs and GC-MS.

In the process of purchasingHigh purity hydrogen generatorWhen doing so, you can refer to the following points:

1. Purity and flow rate

Purity requirement: Determine the required hydrogen purity based on the application scenario. For example:

Gas chromatography/mass spectrometry analysis: purity ≥ 99.999% is required;

Semiconductor manufacturing: Some processes require ≥ 99.9999%.

Flow range: Calculate the total required flow of the computing device and reserve a 20% -30% margin.

2. Pressure stability

Confirm the requirements of the instrument for hydrogen pressure (such as 0.1-0.4MPa), and select equipment with pressure compensation function to avoid pressure fluctuations caused by pipeline resistance.

2. Electrolytic cell technology

Material: 304 stainless steel or titanium alloy electrolytic cells are preferred for their strong corrosion resistance and longer lifespan.

Electrode: Precious metal electrodes (such as platinum and iridium) have high electrolysis efficiency and better stability than ordinary metals.

Ionic membrane: Proton exchange membrane (SPE membrane) technology can avoid alkaline contamination and extend maintenance cycles.

4. Drying and purification system

Drying method: Molecular sieve adsorption can deeply dehydrate to dew point ≤ -60 ℃;

Purification efficiency: Equipped with a palladium tube purifier or catalytic oxidation device, impurities such as oxygen and nitrogen can be further removed.

5. Security protection function

Overpressure protection: Automatic pressure relief valve prevents pressure from exceeding the limit;

Leak detection: Hydrogen sensors monitor leaks in real-time and issue alarms;

6. Redundant design

The dual electrolytic cell system can achieve non-stop maintenance and ensure continuous gas supply.

7. Maintenance cost

Consumable lifespan: The electrolyte replacement cycle and the number of molecular sieve regenerations directly affect long-term costs;
