Helium supplies are diminishing and prices are rising
Feb 28 2014
It’s a fact that helium supplies are running out and worldwide demand is exceeding current production levels. There is also no known solution to this problem. Helium is difficult to find and store in practical quantities and the US helium reserves – where most helium is stored, are now under threat from refinery closures and privatisation.
With increasing global demand from countries such as China and the introduction of new applications using helium, the problem can only get worse.
The global helium shortage and its effects on your industry
As helium supplies reduce, its cost steadily and irreversibly rises. Supplies are also being disrupted by rationing and availability for minor applications such as gas chromatography is being rationed as priority goes to sectors such as healthcare.
Thankfully there is an alternative to using helium that can both save you money and protect you from future scarcity disruption.
Hydrogen – the practical alternative to helium
Unlike helium, hydrogen can be generated easily and inexpensively. The performance of hydrogen at higher carrier gas velocities provides distinct advantages for laboratories to decrease run times and therefore increase sample through put, but without compromising on sample quality.
In addition, hydrogen frequently allows for the use of a lower oven temperature for separation, thereby increasing column longevity.
Safety
GC instrument manufacturers have recommended hydrogen as a carrier gas for several years, and there are multiple safeguards in place to ensure all equipment is safe.
Benefits of In-House Gas Generators
· Cost. Far cheaper than using hydrogen cylinder gas and a fraction of the cost of using helium cylinders. Equipment benefits also include faster analysis, greater resolution and longer column life.
· Safety. Using in-house hydrogen gas generators is a demonstrably safer way to use hydrogen.
· Convenience. With no supply issues, in-house gas generators can supply gas on a 24/7 basis with no requirement for user interaction (barring annual routine maintenance).
Why Parker domnick hunter hydrogen generators are the intelligent choice
The Parker domnick hunter H-MD hydrogen gas generator offers intelligent control and safety alarms, whilst facilitating optimum GC instrument performance, and reduced bottom-life gas costs. With a two-year standard cell warranty and minimal maintenance costs, it’s the cheaper and safer alternative.
