茚三酮优化配方显现汗潜手印的探讨

通过不同茚三酮显现配方在不同纸张上的不同遗留字迹的显现效果比较发现。氟利昂、石油醚茚三酮溶剂在不破坏检材字迹的前提下显现汗潜手印，能够取得预期效果。从保护环境的角度出发。应放弃氟利昂，选择石油醚。通过单因素实验可以得到一种环保且对检材字迹破坏小的茚三酮优化配方。

Probing into the Optimized Ninhydrin Formula Manifesting the Sweat Latent Fingerprints

Comparing the manifestation effect of different handwriting left on various paper manifested with different ninhydrin formula,we find that freon,petroleum ether Ninhydrin solvent manifest sweat latent fingerprints without breaking handwriting samples.Proceeding from the considerations of environmental protection,we choose petroleum ether other than Freon.Through single factor experiments,we can get an optimized ninhydrin formula which not only destroys the handwriting on the examination materials to a least...
