DPL-EVD3500 HAND-HELD EXPLOSIVES DETECTOR $23,900.00
The
technology built into this unit is actually superior to what is offered
in other hand-held explosives detectors and also the cost of
maintenance is lower, less complicated and it detects a wider range of
explosives.
Disadvantages of IMS Systems
IMS
instruments normally contain a small quantity of radioactive material
as an ionizing source. This radioactive source does not pose any health
risks if the system is operated properly, but simply having such a
source may lead to extra paperwork and regulatory oversight.
The
drift time associated with a given ion is dependent on atmospheric
pressure, and can thus change during inclement weather or when the
spectrometer is moved more than a few hundred feet in elevation. These
conditions require little more than routine, periodic recalibration,
but users need to be aware of this issue.
Another drawback of
IMS technology is peak resolution in mixtures or “realworld samples”.
Two different materials that form ions of similar size and mass may
appear as a single broad peak rather than two distinct peaks in an IMS
spectrum.
Disadvantages of GC/SAW Systems:
The
main advantage of GC/SAW detectors is also their biggest disadvantage.
The GC/SAW is nonspecific and the presence of other chemicals may make
explosives detection more difficult. Additionally, a gas container is
necessary for operating the instrument.
Disadvantages of Reagent-based Systems:
The biggest disadvantage of color-based systems is the reliance on the operator’s interpretation of color, as follows:
• Identifying the specific type of explosive present when a positive result occurs is not always possible.
•
Only the specific colors in the instructions can be judged a positive
detection. Other discoloration is possible, but should be judged
negative.
• Operators may have some degree of color blindness.
Additionally, vapor sampling cannot be performed and detection is very dependent on sample concentration.
Disadvantages of GC/MS Systems:
Some MS systems require a gas supply or vacuum pump. The sample analysis time can be relatively long.
Introducing the DPL-EVD3500 Hand-held Explosives Detector. Ready to operate in only 5-30 seconds. The DPL-EVD3500
is the world’s first and most recognized portable explosives trace
detector that uses Luminol Chemiluminescence (Chemilumina). The DPL-EVD3500
is the only portable device capable of detecting the presence of all
threat explosives,including ICAO taggants, military plastics and TATP.

DPL-EVD3500 HAND-HELD EXPLOSIVES DETECTOR does not utilize a
radioactive ionizing source and thus users can avoid some of the
paperwork and possible regulatory oversight that may be associated with
detectors that use radioactive sources.
The DPL-EVD3500
looks for solvent based as well nitro based explosives (90% of
explosives are nitrogen oxide based NO2). The new "Designer bombs"
frequently are solvent based i.e., acetone, peroxide etc. The DPL-EVD3500
catches them all. The technology for the "detection principle" is
Chemiluminescence historically the most proven detection method but
only used in labs in machines that cost $400K and are huge and do not
go in the field. They are considered scientific testing and analytical
equipment.
We have the only patent on this tech in field
hand-held units— This is incredible! It’s the best solution available
in a portable device by a HUGE margin! The competition can NOT come
close to it. It is more selective and sensitive than the EVD-3000 and
ALL other handhelds.
There are far fewer "false positives" from
inaccurate detection of non explosives (false alarms). It has very
advanced software that makes it very easy to operate. It is quite
robust and field worthy. Lasts a lot longer in the field prior to
maintenance. Cleans and clears itself after contamination by a rich
explosive.
The main thing is there is no other device (handheld) that can detect near the variety of explosives the DPL-EVD3500 can.
It
also does not use any external carrier gas or radioactive source
(unlike others). If portability, quick detection and clear, accurate
results are crucial, then this is the explosives detector needed. The DPL-EVD3500
offers extremely fast and stable detection with very high selectivity
for explosives and immunity to humidity or contamination problems. The DPL-EVD3500
detects traces of particulates and vapors, allowing for noninvasive
searches of luggage, mail, vehicles, documents and containers.
Operating the DPL-EVD3500 :
The DPL-EVD3500
is flexible and easy to operate, offering both vapor and particulate
sampling without the use of an external carrier gas or radioactive
source. Vapors are sampled directly via the sampling nozzle.
Particulates are sampled by swiping a suspected object with a cotton
glove or other means and transferring any traces to the unit. This dual
capability enables users to select the most suitable method of sampling
for the explosives of interest. The DPL-EVD3500
starts processing samples immediately and gives results in just
seconds. All results are indicated on the LCD graphical and numerical
display.
* Fast and Proven: The DPL-EVD3500
has proven to be capable of detecting plastic and high vapor pressure
explosives rapidly-giving clear results you can trust. Luminol
Chemiluminescence is an ASTMEPA standard method for atmospheric
monitoring of nitrogen dioxide.
* Sensitive and Selective: The DPL-EVD3500
can detect minute traces (low nanogram level) of C-4, TNT, Dynamite,
PETN, Semtex, EGDN,DMNB, RDX, ANFO, Amonium Nitrate, Urea Nitrate,
Nitroglycerine and TATP, with low false alarm levels and few
interferents.Immune to variations in humidity and environmental
conditions.
* Portable: The DPL-EVD3500
is selfcontained, lightweight, less than 3 kg (6.6 lbs), and comes in a
fully equipped, rugged carrying case -ready to use when and where
needed.
* No Radioactive Isotopes or Radioactivity
* Easy to Use: The DPL-EVD3500
is ready for operation within thirty seconds from turn on. When
necessary,any minimal cleaning takes only a few seconds. The simple
push of a button automatically activates the sampling and analysis mode.
Results are displayed on an easy-to-read LCD making the DPL-EVD3500 ideal for all non-technical personnel. ICAO taggants and tagged plastic explosives.

Future Outlook on Hand-Held Explosives Detection
The
explosives detection techniques discussed here are expected to remain
the principal techniques for use in law enforcement and other
applications
for at least the next several years. The expected trend for new equipment
is
toward more portable, miniaturized units, rather than improvements in
sensitivity. The sensitivity of current instruments is already adequate
for most applications. The miniaturization of equipment will likely
reduce the cost of the equipment. Another possible future trend is to
have systems that combine two or more detection technologies into a
single system.
