The mixed liquor was then sparged using helium to displace dissolved oxygen in the mixed liquor.
Cern The Large Hadron Collider uses helium to keep its equipment super-cooled.
In the present experiment, we use helium to create an asymmetric plasma.
A system using helium gas to absorb some of these vibrations was installed.
It is further shown that, by using helium as the diluent, and by reducing the oxygen concentration of the combustible, diffusional-thermal instability can be mostly suppressed and the hydrodynamic instability delayed.
The first to propose using helium in the place of hydrogen in airships, he helped organize helium manufacture in Italy.
The flow rate was set to 1 ml/minute using helium as the carrier gas.
A capillary column (Agilent Technologies, Santa Clara, CA) was used to separate the analytes using helium as a carrier gas.
The DART interface was operated in positive-ion mode using helium gas with the gas heater set to 200°C.
The amounts of nitrate in the plasma were measured by adding a reducing gent (0.8% VCl3 in 1 N HCl) to the purge vessel to convert nitrate to NO · , which was stripped from the plasma by using helium purge gas.
