Course Overview

Trace

Traces are microscopic amounts of particles and vapors.

Narcotic substances are organic and constantly emit ‘traces’.

The VaporTracer detects traces down to nanogram levels.

The VT2 is just one more tool to help you improve your ability to detect narcotic traces.

Use it along with your X-ray, metal detectors, canine units, physical inspections, and current security measures.

• Traces cling to anything they touch.

• Traces transfer from person to person, person to object, object to object and airborne.

TraceHow Do Traces Get Transferred?

• Cargo, mail, and packages

• Conveyance access - Security access points, border crossings, checkpoints

• Baggage • Facilities protection -

government buildings, correctional institutions

How are traces transferred?

Trace

· Particle – Most reliable method. Uses a different collection procedure.

· Vapor – Certain substances give off less vapor than others. Temperature is a factor for collecting vapor. Sample vapor release points.

SamplingMaterials and Equipment for Vapor Sampling

Person whose item you are sampling should be present.

Sample one item at a time. Use firm pressure. Sample in one direction, one

time. Sample most touched areas

last.

SamplingParticle Sampling Fundamentals

People: Hands Belts Pockets


Vehicles: Door handle Gas cap Steering wheel Knobs Seat Belt Luggage Wherever there

may be a fingerprint.

Avoid sampling engine parts.


Luggage/Bags/Briefcases: Handles Straps Zipper tabs Latches Interior seams and linings Commonly touched areas


Electronic Devices: Vents Seams Battery compartments Disk drives Edges Latches

AVOID SAMPLING: Monitors Keyboards Camera lenses


Sample vapor release points.

Get as close as possible to the vapor release point without touching it.

Temperature affects vapor samples.

Substances emit different levels of vapor.

Equipment Overview

Unit is ready 30 minutes after a cold start.

Unit should be powered-on 24/7.

Default 5 minute warm-up time.

Default 15 minute warm-up time when changing the desorber.

Power down only as directed by pressing the switch to the center position

When do you shut the unit down?

Equipment Overview

Place the sample trap into the desorber. Press the Start button to begin

analysis. When in Vapor mode, hold the Start button for as long as necessary. Analysis begins when the Start button is released.

Maintain control of the item you are sampling.

Observe Ready or Alarm on the display.

Remove the sampling trap. If Ready, reuse the trap. If Alarm,

discard trap and gloves.

AnalysisProcedures

Resolve the alarm in accordance with current SOP.

Examples: Contact your

supervisor. Maintain control of

item. Let the owner know

that further samples may be necessary.

Decontaminate the work area.

Save the alarm by pressing ENTER.

Clear the unit after saving by pressing START.

Decontaminate the work area with alcohol only

The unit must be cleared before additional samples can be taken.

AnalysisSaving Alarms

Make sure the alarm was saved. Press the START button when you

see Ready on the display. Insert a new sampling trap and

press START. If the new trap alarms, inform the supervisor.

In most cases the unit will clear after an alarm. Otherwise, maintenance may be necessary.

Analysis

• Calibration introduces a known substance into the detector for identification.

• After the VaporTracer2 identifies the calibrant, the software will adjust the positions of all substances.

• The VaporTracer2 must be calibrated for accurate detection.

Why Calibrate?

Calibration

• After powering up• After changing modes• At the beginning of each

shift• When the unit is moved • At higher elevations• When atmospheric

conditions change (humidity, pressure)

When Do You Calibrate?

Calibration

Press to begin calibration.
