1,2-Indandione Solution, HFE 7100 Formula

Indandione is extremely sensitive to amino acids in latent finger prints on porous surfaces. It is reported to develop 46% more latent prints than DFO. The consistency and quality make this the best in the industry. Additional Information 1,2-Indanedione, an alternative to DFO, reacts with amino acid residues on porous surfaces like paper, producing weak visible prints but strong fluorescence that is visualized at 520nm with filtration between 570-590nm under green ALS light with orange or red filtration. It is not suitable for poor quality papers such as newsprint or cardboard.
