Product Focus: Laboratory Gas Generators

For David Hemmig, director of equipment sales at Matheson Tri-Gas (Basking Ridge, NJ), the key word in on-site gas generation is reliability. He explains that a major problem with gas generators that incorporate some sort of compressor is that eventually that component fails.

Nitrogen and zero air generators, for example, often use compressors to bring air into the system. The zero air generator “fine tunes” the product by removing hydrocarbons. “But the compressor is the weak link,” Hemmig says.

For nitrogen generators, the compressor serves a similar purpose, but separating pure nitrogen from air (which is 78 percent nitrogen) is slightly more difficult. Membranes represent the established technology, while units from Air Products (Allentown, PA), for example, use pressure swing adsorption. Regardless, when the compressor fails, nitrogen generation ceases.

Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

Biochemical Systems 3000 Evolution
How do I unlock the test method on the 3000 evolution biochemistry analyser? Advise this member.

GE Healthcare AKTAprime plus - Sample tube
We went through a troubleshoot during our cleaning routine with an AKTA PRIME. Once the AKTA was turned off we accidentally hit the green sample tube in the front side (the one that connects the mixer with the pressure sensor), and now it's broken. What we should do? Can we order another sample tube and try to repair it ourselves or is it better to call for assistance? Advise this member.

Thermo IEC Micromax (NV) - Does it need brushes
We have an old Micromax microcentrifuge that sounds rough. With other brands of microfuges, it usually was because it needed new brushes. Not sure what is going on in this case. It is quite old. I don't have the manual, though one would be nice. Advise this member.
