氨基黑10B显现法是一种针对血手印的显现效果好、广泛应用的显现试剂,但由于该试剂以甲醇为溶剂,对长期使用者造成一定伤害。本文经过大量的实验,确定了替代的试剂,经对新配方的适用范围进行实验研究发现,新配方氨基黑10B具有显现效果好、适用客体、手印物质及手印遗留时间范围广泛的特点,经预处理,还可用于渗透性客体表面血手印的显现,试剂稳定,长期放置不变质,可替代原有配方。
Amino Black 10B visualization method is a manifestation of the effect of blood fingerprints is good, widely used imaging reagents, but because of the reagent to methanol as a solvent, cause some damage to long-term users. In this paper, a large number of experiments to determine alternative reagents, the scope of application of the new formula for experimental study found that the new formula Amino Black 10B has a good effect, the applicable object, handprint materials and handprint characteristics of a wide range of time, Treatment, but also for the appearance of blood fingerprints on the surface of permeable objects, stable reagents, long-term placement without deterioration, and can replace the original formula.
