QL-150 hydrogen generator for gas Chromatograph
QL-150 hydrogen generator for gas Chromatograph adopt SPE/PEM technology-top tech in the world. PEM full name is Proton Exchange Membrane. Also called SPE technology ( solid polymer electrolyte).QL series hydrogen generator is our patented products, which are light , highly effective , energy-saving and of environmental protection , producing extremely pure hydrogen (>99.999%) through the electrolysis of pure water (without adding alkali).

Characteristics of the QL-150 gas chromatography use hydrogen generator
1.Electrolysis of pure water (adding no alkali) to produce hydrogen with no corrosion and pollution, and the purity of hydrogen is extremely high.
2.Voltage of unit cell is low, and electric resistance in the electrolysis cell is little, giving out no heat, and cycle of changing desiccants is long, producing highly pure hydrogen.
3.With stable pressure and output, Hydrogen is controlled according to the requirements, and automatic control technology is perfect and reliable.
4.Power consumption is less, and the electrolysis is efficient.
5.H2 flow and pressure is stable
6.Titanium material

PEM hydrogen Technology working principle:
The proton exchange membrane (PEM), which only
allows water and positive ions to cross between
compartments. The membrane also serves as the
electrolyte in the cell, eliminating the need for
hazardous liquid electrolytes such as concentrated
potassium hydroxide. PEM water electrolysis simply
splits pure deionized water (H2O) into its
constituent parts, hydrogen (H2) and oxygen (O2),
on either side of this membrane. When a DC voltage
is applied to the electrolyzer, water fed to the
anode, or oxygen electrode, are oxidized to oxygen
and protons, while electrons are released. The
protons (H+ ions) pass through the PEM to the
cathode, or hydrogen electrode, where they meet
electrons from the other side of the circuit, and
are reduced to hydrogen gas. The two reactions that
occur in the cell are as follows:
2.2H2O -> 4H+ + 4e- +O2
3.4H+ + 4e- -> 2H2
4.Thus, the only possible components of the streams
are hydrogen, oxygen and water moisture, as shown
in
Figure 1 below.
