LATENT PRINT DEV
1,2-INDANEDIONE - CRYSTALS
Suggested use is for developing fingerprint residue (Amino
Acids) on paper and porous items including raw wood and
some currencies. 1,2 Indanedione has a high florescence
when excited by ALS in the 475-590nm range giving greater
clarity and background elimination. Saturate evidence in
1,2 Indanedione solution; allow the item to air dry inside the
fume hood. Latent prints may develop within a few hours or
may take a few days at room temperature. Greater development
may be achieved by sequencing with subsequent
applications of DFO and Ninhydrin. To speed up the development
process, apply humid heat. This is best achieved in a
humidity chamber; Ideal settings are 212oF at 80% humidity
for 15-20 minutes. A steam iron may be used being cautious
not to touch the paper or item directly with the iron as it can
scorch the item destroying the evidence. The acceptable carrier
and formulation is with 3M HFE7100. We have found 3M
HFE 7100 to be the best overall solution for penetration, ease
of use, user and environmental exposure, rapid drying times,
and quality/quantity of developed latents.
THE PROCESS
1. Saturate the Item to be processed by submerging or soaking with a float bottle application.
Spraying 1,2 Indanedione exposes the user to unnecessary risk and does not
saturate as thoroughly.
2. Allow item(s) to air dry within a vented fume hood.
3. Latent prints will begin to develop as soon as 30 minutes after treatment or may
take as long as 48 hours. The exposure to heat and humidity will usually accelerate
the process but prints have developed 24 hours or more subsequent to the heat and
humidity acceleration. As a general rule always allow your evidence 24 hours post
treatment for a complete exam.
4. Developed prints will give high fluoresce between 475nm and 590nm.
