carrier gas การใช้

• The choice of carrier gas ( mobile phase ) is important.
• The ablated particles are collected and incorporated into a carrier gas.
• Therefore, helium is the most common carrier gas used.
• This can be problematic if the carrier gas is pyrophoric or toxic.
• Sample is carried through the apparatus by nitrogen carrier gas.
• Because of the design, the carrier gas can permeate the liquid source.
• The droplets are then transported by a carrier gas to a furnace where they are heated.
• Some thermal desorption systems recycle the carrier gas, thereby further reducing the volume of gaseous emissions.
• The porous membranes cannot prevent the penetration of microdroplets across the hollow fiber into the carrier gas.
• Ozone is delivered ( sparged ) as a gas in either a dry air or oxygen carrier gas.
• The carrier gas linear velocity affects the analysis in the same way that temperature does ( see above ).
• The process involves evaporation of the organic material over a substrate in the presence of an inert carrier gas.
• When a carrier gas is used to deliver water vapor, the carrier gas molecules generate a partial pressure.
• When a carrier gas is used to deliver water vapor, the carrier gas molecules generate a partial pressure.
• Some authorities believe this system was a disc generator with a helium and argon carrier gas and potassium ionization seed.
• Helium remains the most commonly used carrier gas in about 90 % of instruments although hydrogen is preferred for improved separations.
• Bubblers are simple devices that add water vapor to a carrier gas stream as the carrier gas bubbles through a water vessel.
• Bubblers are simple devices that add water vapor to a carrier gas stream as the carrier gas bubbles through a water vessel.
• The output signal is proportional to the concentration of CO 2 in the carrier gas, from the oxidation of the sample aliquot.
• Metal powders are delivered and distributed around the circumference of the head either by gravity, or by using a pressurized carrier gas.
