These QL series hydrogen generators are well-proven, plug-and-play systems designed to produce high-purity hydrogen gas (>99.999%) using advanced proton exchange membrane water electrolysis (PEMWE) technology. With simple power-on operation, users can generate hydrogen on demand, eliminating the need for inconvenient, costly, and hazardous hydrogen gas cylinders. Advantages: High purity of >99.999%, Stable and adjustable gas flow Safe and easy to use with multiple built-in safety alarms, such as overpressure alarm, water shortage alarm, water accumulation alarm etc. Meet the requirements of all kinds of GC Meet CE (Conformité Européenne) requirements Hydrogen outlet: 1/8" Compression Fitting Applications: Gas chromatography carrier gas and fuel gas Hydrogen supply for fuel cell ICP-MS collision gas Hydrogen supply for emissions test equipment Gas analyzer support gas ELCD (conductivity detector) reaction gas AED (atomic emission detector) of reaction gas Other pure hydrogen application field Key Features: Generally, lead time of 4 weeks is expected depending on the model.
