Helium Degassers

 

 

Helium degassing continuously passes helium through a solvent in order to expel dissolved air. This is the most effective method of degassing, and is recommended both for trace analysis and for avoiding the fluorescence quenching due to the effect of dissolved oxygen on the analytes. The disadvantages associated with helium degassing are the high price of the helium and the fact that more volatile solvent components (such as tetrahydrofuran) can also be expelled by the helium over a period of time. This can give rise to changes in retention times.

Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation. Search by Specification | Learn more about Helium Neon Lasers
Carbon dioxide (CO2) lasers use the energy-state transitions between vibrational and rotational states of CO2 molecules to emit at long IR, about 10 µm, wavelengths. These lasers can maintain continuous and very high levels of power and are typically used in cutting, welding, etching, and marking applications.
