Spot.On.ID™

Thin Layer Chromatography is normally a laboratory analytical technique that can separate a sample solution into constituent components, the characteristics of which can then be used to identify substances in the sample solution. The separation occurs on a thin layer of adsorbent, which is called the stationary phase and is fixed onto a backing plate, both of which together is called a TLC plate – a liquid solvent, which moves up the TLC plate stationary phase by capillary action is called the mobile phase. The constituent compounds in a sample solution are carried up the stationary phase by the mobile phase and are deposited, or bound, to the stationary phase depending on their characteristic interaction with the stationary and mobile phase. If a constituent has greater affinity for the mobile phase than the stationary phase as the constituent moves up the plate then the constituent will stay in the mobile phase and keep moving; if a constituent has a greater affinity for the stationary phase at a particular location than it does for the mobile phase, the constituent will bind to the stationary phase at that spot as the mobile phase continues to move up the plate. The resulting constituent compound locations can be compared with reference standards in order to make a presumptive identification or can be compared to a table of what are called Rf values. An Rf value is equal to the distance traveled by the constituent compound divided by the distance traveled by the mobile phase, the value of which is always between zero and one. FFI’s Spot.On.ID™ is a portable system that can easily be used in the field.

• E.L.I.T.E.™ enhanced colorimetric chemistry is unique, giving the user easily discernible colors and false-positive rates lower than other currently available test kits, instruments and even K-9s. There are no known false-negatives.
• E.L.I.T.E.™ doesn’t require an instrument to read the result and since a color change indicates a positive for explosives or a precursor chemical the color chart is only for reference. A digital camera records the result, the kit serial number, date, time, GPS location and other information. Site map overlap Please remove these and place them in the main pic.

• E.L.I.T.E.™ tests for peroxides and chlorates in liquid, vapor or solid form and can even detect peroxide-based explosives such as TATP when the TATP is stored or hidden under alcohol.

• EL100 & EL100EXO

  The EL100 and EL100EXO use a chemistry that requires a heater for part of the test; we have chosen this particular chemistry because of its high sensitivity and low false positive rate; The EL100 uses an automated external heater and the EL100EXO has a built-in solid state disposable heater.

• EL240

  The Model EL240 for chlorates and peroxides has a pen-like design to give operators some finger protection when sampling potentially friction-sensitive explosives.
