  • Patent number: 4757023
    Abstract: The invention concerns a method and an equipment for the simulated distillation, by means of gas chromatography, of petroleum products, capable of characterizing also high boiling products, exceeding C55, over 600 C TBP. A chromatograph is used with a capillary column having a length less than or equal to 10 m, containing an immobilized non polar polydimethylsilicon gum stationary phase with a film thickness less than or equal to 0.2 .mu.m. The sample is introduced through a non vaporizing direct cold on-column injection and the eluted sample is detected by means of a FID detector. The column oven is operated in temperature programming conditions up to temperatures exceeding 400 (up to 430-450 C.).

  • Patent number: 4670262
    Abstract: The present invention relates to the preparation of sterile and stable freeze-dried forms of Cisplatinum containing from 10 to 50 mg of active ingredient, which can be obtained on an industrial scale and which have particular characteristics of facility and rapidity of dissolution which permit them to be used in a more advantageous and rational manner in antitumor chemotherapy, as compared with the freeze-dried forms of Cisplatinum presently on the market.These particular characteristics are achieved as the result of employing special ingredients in respect of formulation (concentration of the solution to be freeze-dried, introduction of alcohols, adjustment of the pH of the solution to an appropriate value), and as the result of using a manufacturing technique having as its final stage the freeze-drying of Cisplatinum in a water-alcoholic medium.
