Application
The primary use of the MO-2D is to identify persons (travelers) who have recently been in contact with explosives. This information is critical for counter terrorism operations.
The МО-2D is designed to detect traces of explosives directly from documents (passports, ID, credit cards, etc.). It is also used to detect traces trace of explosives collected from other objects using sampling cards.
The analyzing process automatically starts when a document is placed into the reception slot (desorber): warm air is blown on the document to desorb volatile substances from it; the air flow then carries the vapors into the detector’s analytical channel for analysis.
The presence of explosives generates a detection signal and triggers alarms.
Special features
The detector is controlled by a Pocket Personal Computer (PPC).
The special IoScanPPC software performs the following functions:
- Control of the detector’s main elements; - Data acquisition and processing; - Display of the results of inspection (ionograms) and data storage for further analysis; - Exchange of data with external computer.
For objects that generate an alarm, it is possible to collect additional samples for further analysis using the GCS-02F Portable Gas Chromatograph for very precise identification (forensic quality) of the detected compounds. For that, MO-2D and GCS-02F use the same air sampler and concentrators to collect samples.
The MO-2D detector does not contain any radioactive material; the ionization of the vapors is realized by a low energy soft X-Ray lamp. There is no need to coordinate the exploitation of the detector with sanitary services.
