2011年10月10日 · The addition of catalytic amounts of zinc chloride to the 1,2-indanedione working solution – usually in the order of 1:25 to 1:4 molar ratio (indanedione:zinc) – significantly improves the colour and luminescence of fingermarks treated under dry conditions but appears to have a negligible effect on fingermarks treated in humid environments.
1,2-Indandione - Wikipedia
1,2-Indandione is an organic compound with the molecular formula C 6 H 4 (CO) 2 CH 2. A yellow solid, it is classified as a vicinal diketone on an indane framework. [1] 1,2-Indandione is used in the first stage of forensic identification of latent fingerprints. It is particularly useful for paper, and for items printed with thermal inks such as ...
