POWDERS<br />
• The SupraNano powders li well and have much less propensity to smudge on acetate sheet<br />
• In general SupraNano powders are finer and give a much smoother applica on.<br />
• The SupraNano black magne c powder gives much less background staining.<br />
• The SupraNano Black powder can be enhanced with a sweeping mo on while the excess is removed using<br />
a clean brush.<br />
• SupraNano magne c powders also work well with large flat magne c wands.<br />
• SupraNano Fluorescent magne c powders with UV light are ideal for use on busy backgrounds e.g. paper<br />
currency giving good contrast and defini on.<br />
SUPRANANO SUSPENSION SPRAY<br />
• The suspensions are at their best in outdoor scenes that have been we ed and dried or are s ll wet.<br />
For example the outside of vehicles, UPVC windows/doors, glass, painted surfaces like fences and<br />
even engineered/glazed bricks. Any semi smooth, no-porous/semi porous surface can be sampled.<br />
• The Black suspension has been shown to work successfully on painted surfaces and Zinc coated security fences.<br />
• The suspensions are designed to fluoresce at different wavelengths within the light spectrum while elimina ng<br />
background interference under certain wavelengths. For example the Yellow Suspension is highly fluorescent<br />
under UV long wave and blue light (300 – 450 nm) and is an excellent choice for many surfaces. The Green<br />
Suspension is op mal under blue light (400 – 450 nm) and can be filtered using a band pass filter (yellow 470nm) for more specific searching.<br />
Suspension Spray User Guide:<br />
1. Shake the bo le to suspend the par cles. (Ensure that<br />
the bo le nozzle is set to OFF in order to prevent spla er<br />
when shaking)<br />
2. Switch the nozzle bo le to SPRAY and aim the<br />
suspension at the desired surface that you wish to<br />
develop ridge detail on. On large surfaces start at the<br />
bo om and work your way up sampling areas about<br />
50cm x 50cm.<br />
3. Gently spray the suspension evenly across the surface,<br />
allow to run down the surface for a few moments and to<br />
fully soak the area.<br />
4. The spray can be concentrated on areas to build up<br />
ridge detail as needed for weak marks.
