1. Hydrogen is produced by electrolysis of deionized water across a PEM (Proton Exchange Membrane) incorporated in a 100% titanium electrolytic cell. 

2. The resultant hydrogen is purified using a combination of gas liquid separation and a unique Nafion drying membrane. This produces 99.9996% purity gas ideal for all GC detector applications.

3. For the higher purity NM Plus versions, a third stage patented automatic cold dual dynamic dryer increases the purity to 99.99996%, ideal for all GC and GC/MS carrier gas applications.

4. For generators incorporating Zero Air, a separate supply of compressed air is purified using a combination of filtration and a heated catalyst to remove hydrocarbons to <0.1ppm. 

Whisper (+ Hybrid)
1. A standard supply of compressed air is filtered by high efficiency coalescing filters to remove all contaminants down to 0.1 micron. A unique proprietary hollow fibre membrane then separates the air into a concentrated nitrogen stream.

2. Nitrogen diffuses through the membrane slower than O2, CO2, CO, etc. leaving a supply of high purity, clean and dry gas.

Mistral Evolution Gas Station Nitrogen Generator (+P-E)
Mistral Evolution Hybrid Nitrogen Generator
1. Nitrogen is produced by utilizing a combination of compressor, filtration and CMS (Carbon Molecular Sieve) technology.

2. High and low pressure compressors are carefully matched to the CMS demand to ensure quiet and reliable operation. 

3. Nitrogen is produced at low pressure, which ensures a longer compressor life, and then compressed to 8 bar using a second stage compressor. This combination guarantees a long compressor life reducing maintenance costs and down time.

4. For the specialist hybrid version, air is produced using an additional third stage compressor maintaining a separate constant flow and pressure.

HP Plus Tower Nitrogen (+HC Removal Generator)
1. An external supply of compressed air is purified using a combination of filtration and CMS (Carbon Molecular Sieve) technology. 

2. Using a specialized process, the CMS is filled into twin tower PSA (Pressure Swing Adsorption) system.

3. The continuous adsorption and de-adsorption produces a supply of ultra-high purity nitrogen.

4. For GC applications, the optional catalyst removes hydrocarbons to <0.1ppm/

GC Plus Zero Air Generator
1. An external supply of compressed air is purified using a combination of filtration and catalytic oxidation technology.

2. The first stage of filtration removes water, oil, and particulate to <0.1ppm.

3. The air then passes across a heated platinum catalyst which removes the hydrocarbons to <0.1ppm.

4. A final high-efficiency filter ensures an ultra-high purity, hydrocarbon and particulate free air supply.

GT Plus Ultra Zero Air Generator
1. An external supply of compressed air is purified using a combination of filtration and catalytic oxidation technology.

2. The first stage of filtration removes water, oil, and particulate to <0.1ppm.

3. A no maintenance PSA (Pressure Swing Adsorption) system filled with a molecular sieve removes CO2, CO, and water vapor.

4. Specialist carbon filters the NOx and SOx.

5. The air then passes across a heated platinum catalyst which removes the hydrocarbons to <0.1ppm.

6. A final high-efficiency filter ensures an ultra-high purity, hydrocarbon and particulate free air supply.
