Programs 1 through 3 offer three factory default options for common CA fuming
methods. These first three programs can be modified, and then run; however, the
program changes will not be saved. You can modify and save changes to Programs 4
through 20. The default parameters for Programs 1 through 3 are listed below in Table
5-1 along with a description for their use.
It is recommended to use a low viscosity Cyanoacrylate (very fluid like water) for best
results. Default Programs 1 and 2 are developed for use with a low viscosity
Cyanoacrylate. Arrowhead Forensics A-2601 CA was used to develop these first two
programs. Using a different CA, particularly a higher viscosity CA, may require
adjustments to the program parameters for best results.
Program 3 is developed for use with Lumicyano
TM
, which is a CA product with a dye that
fluoresces under a special laser and curved orange photography filter system. This
product can provide better contrast for developed fingerprints. Using a different CA
product with dye stain may require adjustments to the program parameters for best
results.
There are several factors that affect the outcome of the CA fuming process. These
preset Program options are just a helpful starting point for the end user. You will need
to test these setting and make adjustments as needed due to the specific glue, or
environment you are operating in.
