Application

The fields of application of the Detector of explosives traces on documents MO-2D are security and counteraction to terrorism and illegal circulation of explosives by identifying individuals who had contact with explosive substances.

MO-2D detector is designed to detect explosive traces directly on the documents (passports, identity cards, plastic cards, etc.) and/or on the samples, collected at sampling cards from the surfaces of the inspected items.

Principle of operation

The detector’s operating principal is based on Non-Linear Dependence of ion Mobility on an electric field (NLDM).

Inspected document is placed into the document receiver chamber where the document’s surface is heated by a flow of warm air. As a result, the particles on the document surface start to evaporate, forming vapors.

The formed vapors are delivered to the detector’s analyzing channel where they are ionized by the X-ray source (lamp). Then the ions are separated according to their mobility in the electric field, whose parameters are chosen in such a way that the detector’s electronic circuit records the ions of certain substances only.

At detection of explosive traces on the inspected document the alarm signal is generated. The analyzing channel’s parameters are adjusted automatically in accordance with the environmental temperature and humidity changes.

Special features

Availability of the specialized program that provides:
- control of the detector’s units operation;
- data acquisition and storage;;
- presentation and storage of ionograms with the results of analysis;
- data transfer to an external computer.

For identification of the explosive type there is a possibility of sampling and storage of the samples for their subsequent analysis with the "GCS-02F" Portable Gas Chromatograph, produced by Sibel Ltd.

MO-2D detector may operate around the clock without switching the power off.

MO-2D detector does not contain radioactive materials.

Operation with the MO-2D detector does not require coordination with the local bodies of sanitary control.
