The Advanced Technology Purifier (ATP) can purify up to 30 liters of helium gas per minute. At this pace, it is the system of choice for providing clean helium gas to Quantum Design’s Advanced Technology helim Liquefiers (ATL). ATP-cleaned helium gas has an ultra-high purity of 99.9995% or better. Like the ATL, the ATP is fully automated and can regenerate in five hours. One ATP is normally sufficient to deliver enough clean helium gas for two ATL160 liquefiers and is used in the high pressure recovery system.

- Fail safe operation
- Automated regeneration procedure
The ATP30 uses a Gifford-McMahon (GM) cryo-cooler to freeze out impurities like nitrogen and oxygen in the helium gas. The GM cryo-cooler has a closed helium gas loop that is pressurized by a compressor. The compressed helium gas is then expanded in the cold head of the purifier which generates low temperatures that cool down the dewar and the helium gas inside. The helium purifier has no sophisticated installation requirements and can easily be operated in any laboratory. A touch-screen panel allows easy control of the automated system. The ATP30 is part of the high pressure recovery system, which catches helium boil off in a gas bag and stores it in gas cylinders, which are pressurized by a high pressure helium gas compressor. In the high pressure recovery impurities like oxygen and nitrogen diffuse through the plastic gas bag and into the helium gas. These impurities are separated from the helium gas by the ATP30, so the clean helium gas can be liquefied again.

As the ATP30 is used to supply the ATLs with clean helium gas, it is used everywhere where the ATLs are used, for example for the recovery of liquid helium in magnetism and cryotechnology with Quantum Design products like the MPMS and PPMS, with Magnetoencephalography (MEG) systems by Elekta and with Nuclear Magnetic Resonance (NMR) systems by various suppliers. Other equipment that runs with the liquid helium from our ATLs are bath and flow cryostats of any kind for measurement methods like Atomic Force Microscopy (AFM), Scanning Tunneling Microscopy (STM), Fourier Transform Mass Spectroscopy (FT-MS) , Electron Paramagnetic Resonance Spectroscopy (EPR), Cathodoluminescence, Mossbauer Spectroscopy, IR Detectors und Electron Beam Ion Traps (EBIT). As soon as the helium gas gets contaminated due to recovery lines not made from metal the ATP30 should be used to clean your helium gas before feeding it into the ATLs.
