carrier gas , auch: carrying gas

The carrier gas is sent through the central channel and into the very hot plasma.

Because of the design, the carrier gas can permeate the liquid source.

The carrier gas should also be able to withstand high temperatures due to the oven.

Therefore, helium is the most common carrier gas used.

The choice of carrier gas (mobile phase) is important.

This can be problematic if the carrier gas is pyrophoric or toxic.

There are two main parameters in the processes, temperature and flow rate of the carrier gases.

The carrier gas linear velocity affects the analysis in the same way that temperature does (see above).

Many chemists use Argon as a carrier gas to make the plasma.

They must use helium as a carrier gas.

Upon switching, the contents of the sample loop are inserted into the carrier gas stream.

The trap is then heated and the volatiles are directed into the carrier gas stream.

Helium is a commonly used carrier gas for gas chromatography.

When He is used as the carrier gas, the ionization process occurs by the following mechanism:

Helium was used as the carrier gas.

Other parameters that can be used to alter the order or time of retention are the carrier gas flow rate, column length and the temperature.

Typical carrier gases include helium, nitrogen, argon, hydrogen and air.

To increase the delivery rate, the carrier gas flows need to be increased, slowing the diffusion of water vapor to the surface.

In selecting a carrier gas it is important to select a gas that will not react with the components of the sample.

The column inlet (or injector) provides the means to introduce a sample into a continuous flow of carrier gas.

The US and many states have delegated the power of eminent domain to common carrier gas pipelines.

Ozone is delivered (sparged) as a gas in either a dry air or oxygen carrier gas.

The carrier gas flow is not interrupted while a sample can be expanded into a previously evacuated sample loop.

The porous membranes cannot prevent the penetration of microdroplets across the hollow fiber into the carrier gas.

The purity of the carrier gas is also frequently determined by the detector, though the level of sensitivity needed can also play a significant role.
