Gas Generators

Gas generators are essential components in the process of gas chromatography, replacing compressed air with a gas of your choice, very often high-purity nitrogen, but also hydrogen or a vacuum. These systems are engineered to utilize pressure swing adsorption for the removal of oxygen, carbon dioxide, and water vapor. After the gas of choice is purified, the gas is filtered through high-efficiency coalescing prefilters and a 0.01µm membrane filter. Some models are sized to fit in small cabinets or beneath most work surfaces.
