Why is my Ahura FirstDefender taking a long time to complete a scan?

Applies to: Chemical and Gas FirstDefender (Raman) | Tickets Solved: 0 | Rank: 4

There are several factors that affect the length of the Ahura FirstDefender scan.

If you are performing a regular scan, ensure the unit is in Auto mode and not in Library Mode.
If you are conducting a point-and-shoot scan, make sure the vial compartment is empty.
If the substance has a weak molecular signal, is emitting fluorescence, or is present at very low concentrations; the unit will need several minutes to analyze.
To determine the relative strength of the molecular signal and fluorescence, press the down arrow during the scan. A screen will appear showing the molecular signal strength and fluorescence.
If you are scanning a powder on a hard surface, a solid material, or a droplet of liquid; use the signal meter to help determine the best spot to point the instrument.
