Gas generators have many advantages over gas cylinders, as shown in the comparison table. They provide comfort by producing gas on-demand with low maintenance requirements. Gas generators also offer uniform and consistent high nitrogen purity, fast payback, low running costs, continuous and unlimited gas supply. In terms of safety, gas generators require minimal gas storage with low-pressure gas storage, which eliminates the risks associated with the transport, storage, and handling of gas cylinders. Furthermore, gas generators are environmentally friendly, as they do not require delivery or collection, are energy-efficient, and have a low carbon footprint. Overall, gas generators provide a reliable, cost-effective, and safe alternative to gas cylinders for laboratory and analytical applications.

Our in-house Gas Generators

An LC-MS instrument in a typical analytical laboratory, works almost 8 hours per day, an average of 20 L/min of volume flow is needed, 25-30 cylinders are used to fill this consumption. At first, you might think that using cylinders is cheaper than a nitrogen generator, every cylinder needs a minimum of 10-15 minutes time to be replaced safely, 5-6 hours are consumed monthly to replace them.

Our products, the HF-series Nitrogen generators, are specifically designed to meet the high-flow and consistent purity demands of LC-MS instruments and other analytical instruments. We take great pride in the meticulous attention to detail that goes into every aspect of our products, from using our own high-quality, oil-free air compressors to selecting the most reliable components. Our goal is to ensure that our customers have the best experience with our generators, providing a dependable and cost-effective source of high-purity Nitrogen for their critical applications.
