It is much easier to check on the prints if your container has clear sides. So if the print is more than 24 hours old or if the air is very dry, then you need to put a small warm water reservoir in the fuming chamber. A chamber could be a fish tank, a plastic bag held up by PVC pipe, or a commercial chamber. Had a virtual double with a similar name. D. Superglue fuming, The ACE-V process requires an independent examination by a second examiner. Over-fuming is a little more complicated. Superglue should not be placed on a hot plate because it can get too hot and generate HCN (a toxic gas). R. Thumb R. Middle R. Little L. Index L.

Now it is time to assemble the fuming chamber. endstream endobj startxref Ideally, the foil boat will be subjected to uniform heat across the entire boat, allowing an even vaporization of the CA. The heat source must, of course, be level to avoid mounding of the glue, and the foil boat must be of sufficient size to allow the glue to spread evenly across the interior surface of the boat. Under-fuming can be a problem when users stop the fuming cycle before the latent prints have fully developed.

Powered by Invision Community. In the lab, An airtight tank, known as a fuming chamber use to heat up superglue (liquid cyanoacrylate) which releases gases that adhere to the oily residue of print, thereby creating an image of the fingerprint. This helps to develop the print faster.
