Proton OnSite

"More laboratories are opting to generate their own gas, on-site," said John Speranza, Vice President of Global Sales at Proton OnSite.  "For Gas Chromatographers (GC) who are struggling to source inexpensive helium gas, hydrogen is the superior carrier gas alternative..."

"But stored hydrogen is dangerous and purity is always an issue with from a cylinder, so generating hydrogen on-site is the safest, most convenient and purest way to source gas, when it's needed."

Speranza noted that more Liquid Chromatography/Mass Spectrometry (LC/MS) practitioners are also deciding to generate nitrogen gas on-site as opposed to having cylinders delivered.  He said: "LC/MS experts need to know that they have enough high purity nitrogen on hand, at all times.  Gas-hungry LC/MS systems mean cylinders are constantly being replaced, and in a busy lab that can be a hassle and can put results at jeopardy.  By having a pure and cost-effective source of nitrogen gas on hand at the flick of a switch, practitioners can stop worrying about their gas supply and instead focus on getting the best results.

Safer, purer hydrogen generated on-site

The Proton OnSite line of hydrogen generators is the simpler, more cost-effective, and safer approach to supplying hydrogen for all laboratory applications.  Offering units that produce from 300 cc/msn to 18.8 slpm of gas, these generators use Proton OnSite's patented Proton Exchange Membrane (PEM) electrolysis technology to produce gas at +99.9999 percent purity without the need for liquid hydrogen tanks, or compressed gas storage.  It's the safe, cost-effective hydrogen gas solution for any lab.

Proton OnSite's large PEM electrolyzers are the only generators in the laboratory market with the ability to run as a 'Lab Server'.  One S-Series hydrogen generator can supply up to 200 GC units with ultra high-purity hydrogen gas that can be maintained and managed from a single source.  Proton OnSite's technology can also ensure that pressure, flow and purity are constant throughout the building, and can be monitored at all times.

Ensuring safety is paramount for a facility that deals with thousands of liters of hydrogen gas each day, considering a single hydrogen cylinder storing 6,300 liters of gas has the explosive potential of 35lbs of TNT.  A facility with hundreds of GC systems fed by cylinders of hydrogen has a tremendous explosive potential, so a lab manager that opts for delivered cylinders has to invest in significant safey infrastructure to mitigate those risks.  By replacing those cylinders with one or more Proton OnSite hydrogen gas generators, which only produces gas when necessary and have a limited capacity, labs can demonstrably reduce both the explosive potential and the amount of time and money spent handling heavy, dangerous cylinders.

On-site nitrogen, at the flick of  a switch

Proton OnSite's line of on-site nitrogen gas generators use membrane technology and Pressure Swing Adaptation (PSA) systems to produce pure and cost-effective nitrogen gas.  Proton OnSite's membrane generators offer 34, 60 or 120 liters/minute at up to 99.9 percent purity without an internal compressor, and 34 liters/minute with a compressor.  Proton OnSite also offers nitrogen generators that use its own PSA technology to create high-purity nitrogen from compressed air for both LC/MS and GC applications.  These generators product ultra high purity nitrogen at flow rates from 500cc/minute to 9 liters/minute at up to 99.999 for GC applications.

Producing nitrogen gas on-site ensures an optimum flow and supply.  The typical mass spectrometer demands between 1.5L and 2.5L per minute of nebulizer gas, which adds up, especially if a laboratory is running a test for eight or even 24 hours.  As well as a stable supply, MS demands a stable flow.  A mss spectrometer may demand as much as 100PSIG of feed pressure to ensure flow controllers through the system work properly without that constant pressure, it an take a lot longer to get a stable gas flow.  Using cylinders that have to be regularly replaced means a flow may not be maintained and the spetrometer's detector may not pick up ions being passed through the system.

On-site generation for all lab gas needs

In every GC and LC/MS application, for practical, financial and safety reasons, on-site gas generation is a must.  By operating a compact, efficient gas generator, lab managers can stop worrying about gas deliveries and gas safety concerns, while practitioners can focus on the job at hand and get better results from a purer, constant carrier gas supply.
