11. Excess ethylene and olefin diluent are flashed off. 12. It is used as a diluent for tributyl phosphate ( TBP ) in reprocessing plants. 13. A non-polar diluent favours the formation of uncharged non-polar metal complexes. 14. The amount of thickener can be decreased to 1 % if other diluents are added. 15. The diluent is usually a gas blend that can be used for bailout if necessary. 16. Bulk slurry ( or bulk ) : Uses liquid propylene instead of liquid inert hydrocarbon diluent . 17. The polymer does not dissolve into a diluent , but rather rides on the liquid propylene. 18. The diluent could be either liquid nitrogen or helium depending on the depth of the dive. 19. Diluents are also used in vaccines to reconstitute the vaccine after storage, such as MMR.20. Quantity not sufficient implies that the final volume of diluent is not sufficient for molecular testing.
