41. This is done by combining a liquid diluent with the freeze-dried powder, mixing, then injecting. 42. The deeper the diver dives, the more diluent is added, and thus the leaner the mix is. 43. Following the spill, the volatile hydrocarbon diluents evaporated, leaving the heavier bitumen to sink in the water column. 44. When the diluent is known ( as is the case for a chemical formulation ), additional diluent can be prepared. 45. When the diluent is known ( as is the case for a chemical formulation ), additional diluent can be prepared. 46. This is done by adding a diluent that lyses the cells which is then pumped into a spectro-photometric measuring cuvette. 47. Adding diluent can prevent the loop gas mixture becoming too oxygen rich, and adding oxygen is done to increase oxygen concentration. 48. To reconstitute and use the product, it must then be mixed with a diluent for reconstitution such as water or saline. 49. Forty-four drugs, diluents , flavouring agents and emollients mentioned by Dioscorides are still listed in the official pharmacopoeias of Europe. 50. In this case the actual breathing mixture varies with the depth, and is made up of a diluent blend mixed with oxygen.
