Ethanol concentrations in the coagulated blood of a bovine, a rabbit and a human were measured by using PY-GC/MS attached with a double-shot pyrolyzer (Model PY-2010D, Frontier Laboratories Ltd., Japan). Pyrolysis of samples was performed at 260°C, and the vapor evaporated from the sample was introduced into the GC/MS directly. For the control experiments, the concentrations of ethanol in both the heparinized bovine and rabbit blood, and homogenized human coagulated blood were measured by headspace-GC.<br>   The values of ethanol in the coagulated blood of the bovine, the rabbit and the human obtained by PY-GC/MS analysis were almost equal to that of the control experiments. These results indicated that the method using PY-GC/MS could be useful to the ethanol analysis of the coagulated blood in a practical case. In addition, the overall analytical time was about 10 minutes and the sample volume necessary for analysis was only 1 mg.<br>

The method studied in this paper is developing latent fingerprints based on ruthenium tetroxide (RuO4) method. Ruthenium tetroxide fuming promptly react with various organic compound, particularly oils or fats contained in sebaceous secretions in latent print and producing brownish black or black ruthenium dioxide (RuO2).   Ruthnium Tetroxide is yellow, volatile crystails (melting point; 25.5°C, boiling point; 100.8°C) at room temperature.   Conventional methods using RuO4 have been almost impractical because it is very difficult to handle by its strong oxidizability. Additionally because of the two liquid method, it is not only troublesome to produce RuO4 fumes immediately before developing latent fingerprints, but also is difficult to produce necessary ammounts of RuO4 fumes.   In this method, these problems were resolved by utilizing a saturated hydrocarbon halogenid solution of RuO4
