| 1. | The choice of carrier gas ( mobile phase ) is important.
|
| 2. | The ablated particles are collected and incorporated into a carrier gas.
|
| 3. | Therefore, helium is the most common carrier gas used.
|
| 4. | This can be problematic if the carrier gas is pyrophoric or toxic.
|
| 5. | Sample is carried through the apparatus by nitrogen carrier gas.
|
| 6. | Because of the design, the carrier gas can permeate the liquid source.
|
| 7. | The droplets are then transported by a carrier gas to a furnace where they are heated.
|
| 8. | Some thermal desorption systems recycle the carrier gas, thereby further reducing the volume of gaseous emissions.
|
| 9. | The porous membranes cannot prevent the penetration of microdroplets across the hollow fiber into the carrier gas.
|
| 10. | Ozone is delivered ( sparged ) as a gas in either a dry air or oxygen carrier gas.
