Voorbeeldzinnen

1. Liquid nitrogen
2. Dewar flask with liquid nitrogen
3. UAN is a liquid fertiliser supplying nitrogen to crops.
4. During extraction air above the liquid shall be replaced by nitrogen (avoid excess pressure by loosening the stopper from time to time).
5. The sample can be cooled with liquid nitrogen or dry ice, but care should be taken to avoid condensation of air or pump-fluid.

9. A black, viscous, highly complex liquid combination composed primarily of aromatic and partly hydrogenated aromatic hydrocarbons, aromatic nitrogen compounds, aromatic sulfur compounds, phenolic and other aromatic oxygen compounds and their alkyl derivatives.)
10. (The product obtained by filtration of coal mineral matter and undissolved coal from coal extract solution produced by digesting coal in a liquid solvent. A black, viscous, highly complex liquid combination composed primarily of aromatic and partly hydrogenated aromatic hydrocarbons, aromatic nitrogen compounds, aromatic sulfur compounds, phenolic and other aromatic oxygen compounds and their alkyl derivatives.)

15. All noble gas detectors in their modular housing should therefore either be able to operate under a variety of ambient climate conditions without the problem-loaded operation of liquid nitrogen or use electrical power for thermo electrical cooling (if it is needed).
