We Supply a wide variety of lab gas generators & laboratory nitrogen generators for gases such as hydrogen and nitrogen. Nitrogen generators are available at low cost throughout the UK
High Purity Hydrogen Lab Gas Generators
The IATT AiroGen® Laboratory Generator rangeoffers a safe and simple to use efficient technology for high purity H2, N2 and ZERO AIR analytical grade laboratory gases. The technology makes the gas cylinder redundant and the high purity gases you require available as and when you need them. IATT AiroGen® Lab GasGenerators offer a module design and can also be stacked to meet compact storage requirements, this makes them perfect for usage within multiple generation applications.
What is Adsorption?
To fully understand lab gas generators and swing adsorption technology, we must first explore what adsorption is. Adsorption refers to a gas application such as nitrogen generation, and is the accumulation of molecules of oxygen and other trace gases.
This accumulation is used to form a thin film on the surface of a specifically selected solid, such as carbon, by intermolecular forces. The adsorption process involves a mass transfer and differs from absorption, where a specific fluid is dissolved by a liquid or solid. Adsorption is a reversible process and facilitates the constant use of the system to generate nitrogen on a sustainable scale for commercial use.
Nitrogen Generators and Nitrogen Generation Explained
Now, with the definition out of the way, let’s explore how nitrogen generators and the process of nitrogen generation work. PSA Nitrogen is generated the process of adsorption, where the adsorptive properties of specific media, such as a Carbon Molecular Sieve, are used. Oxygen and other trace gasses found through the process are consequently adsorbed onto the adsorptive media at varying portions, depending on the system pressure present. In turn, the nitrogen passes through the media because of the fact that its molecular structure is too large to infiltrate the fine permeability of the adsorptive media in question.
The system utilised within our lab gas nitrogen generators and the generationprocess in general is with two pressurisedtowers to contain the adsorptive media. Here, the clean dry compressed air enters at the bottom of one of the towers where oxygen, carbon dioxide, moisture, some hydrocarbons, and trace gases are adsorbed. Nitrogen then passes through the adsorbent media bed into a buffer tank, prior to the outlet where it is subject to additional filtration and pushedon for use in the analytic application. After a predetermined time which isdependant on the purity of nitrogen required, the tower switches to regenerative mode and streams the pressurised compressed air into the second tower.
This is where the term Pressure Swing originates and is put into action.
Then, the process begins again. The first tower finally depressurises, and the adsorbed oxygen and other trace gases are distributedand expended to atmosphere.
