A crystal, or polycrystal (polycrystalline) material from which larger crystals of the same crystalline structure grow from. Typically, the seed crystal is a small scale crystal from
Sample evaporation
The temperature and pressure at which a sample becomes gaseous in composition.
Sample concentration
The purity or amount of a given component in a sample. Nel hydrogen gas generators have the ability produce hydrogen at a concentration of 99.999995% hydrogen. With
Tube trailers
Used to transport or store large quantities of pressurized gas, or liquid gas, in cylinders or other vessels. These cylinders are attached to a trailer.
Thermal spray
A technique used to coat an object or surface by melting a coating material and spraying it at a high velocity onto a surface. There are many thermal spraying
Ultra pure
Used to transport or store large quantities of pressurized gas, or liquid gas, in cylinders or other vessels. These cylinders are attached to a trailer.
Welding
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by creating a fusion.
Water electrolysis
Water Electrolysis is the process of splitting water molecules (H2O) into oxygen (O2) and hydrogen gas (H2) with electric current passing through the water. Two of
Zero-inventory design
No required storage or build up. The unit only uses what is required at the given time. This eliminates the risk and need for storing
Zero-emission fuel
Emits no pollutants or waste product when burned or utilized. Hydrogen is a zero-emission fuel because it only produces heat and water when utilized in a fuel cell.
Zero air generator
Generators that produce air with low hydrocarbon contents in order to perform analysis. Zero air generators are designed to utilize existing air sources and produce on demand.
