Способ выявления следов рук, включающий обработку следов рук направленным потоком реагента, посредством которого следы становятся видимыми, отличающийся тем, что обработку проводят аэрозольным составом, содержащим нингидрин, кетон с метальными или этильными радикалами, органический растворитель нингидрина, уксусную кислоту и диэтиловый эфир.2. Способ по п. 1, отличающийся тем, что обработку проводят с использованием аэрозольного баллончика, при этом в качестве пропеллента используют фреоны различных марок, пропан-бутановая смесь или азот под давлением.3. Способ по п. 1, отличающийся тем, что используют аэрозольный состав, содержащий (мас.%):4. Способ по п. 1, отличающийся тем, что используют ацетон или метилэтилкетон.5. Способ по п. 1, отличающийся тем, что в качестве растворителя нингидрина используют этиловый или изопропиловый спирт.6. Способ по п. 1, отличающийся тем, что распыление аэрозоля проводят с расстояние 0,20-0,25 м от поверхности с отпечатками рук.1. A method for detecting hand traces, including treating hand traces with a directed reagent flow, through which the traces become visible, characterized in that the treatment is carried out with an aerosol composition containing ninhydrin, ketone with methyl or ethyl radicals, an organic solvent of ninhydrin, acetic acid and diethyl ether. 2. The method according to claim 1, characterized in that the treatment is carried out using an aerosol spray can, while freon of various grades, a propane-butane mixture or nitrogen under pressure are used as a propellant. The method according to p. 1, characterized in that the use of an aerosol composition containing (wt.%): 4. A method according to claim 1, characterized in that acetone or methyl ethyl ketone are used. The method according to claim 1, characterized in that ethyl or isopropyl alcohol is used as the ninhydrin solvent. The method according to claim 1, characterized in that the spraying of the aerosol is carried out from a distance of 0.20-0.25 m from the surface with handprints.
