Building Protection - Ion Mobility Spectrometer
Building Protection - Ion Mobility Spectrometer
Advanced building and air condition protection are more important than ever!
In 1995 the Sarin nerve agent attack on Tokyo¡¯s subway caused the death of 12 people and more than 5,000 got wounded. Since then, with the beginning of the new millennium, terrorism has risen to another height with many attacks on buildings, trains and public places world-wide. The recent attacks show, that the response time of an effective protection system must be very short to evacuate people safely.
The Building Protection-Ion Mobility Spectrometer (BP-IMS) is an ultra-fast and high sensitive gas detection system for the protection against terrorist attacks where Chemical Warfare Agents (CWAs), Toxic Industrial Chemicals (TICs) or Explosives (TATP) are involved.
Chemical Warfare Agents (CWAs)
Toxic Industrial Chemicals (TICs)
Explosives (TATP)
Sarin (CWA) N-Mustard (CWA) HCl (TIC)
Tabun (CWA) S-Mustard (CWA)


Soman (CWA) Lewisite (CWA) Phosgene (TIC)
VX (CWA) Chlorine (TIC) TATP (Explosives)
Integration of the BP-IMS into your Security System
Through the availability of multiple interfaces, it is easily possible to integrate the BP-IMS into different types of building management systems.
Next Generation¡¯s BP-IMS offers several Advantages:
(1) Facility protection

- Continuous protection 24/7/365
- Very high sensitivity in the lower ppbv-range
(2) Detection of CWAs and TICs
  - Custom tailored detection list
- Tracks variants of traditional CWAs
- Monitors concentration levels of TICs
(3) Reduces cost of ownership
  - Positive and negative polarities allow a dramatic cost reduction for comprehensive facility monitoring
- No carrier gas required
- Low-cost preventive maintenance concepts (Self-check routines)
- Automatic steering: Data acquisition, event and alarm logs
(4) Easy system integration
  - Fits into standard 19¡± rack system
- Easy interface into facility management systems
- Flexibility: Supported by digital, analogue or relay outputs

The BP-IMS system is a full automatic trace gas analyser based on Ion-Mobility-Spectrometry (IMS) with very high sensitivity in the lower ppbv-range.

The BP-IMS is designed as a standalone and portable device with a tandem IMS and two closed gas-circuit systems.
Both gas-circuits are equipped with an automatically working valve system.
Sampling through integrated pumps into both detectors, flow rate up to 2,000 ml per minute.
Simultaneous detection in positive and negative polarity.
Separate temperature control for both ion mobility spectrometers (default 45¡ÆC).
Manual or full-automatic operation mode with data acquisition, data-analysis, data-visualisation and data-transfer to external devices.
Full running time per measuring cycle is less than 5 seconds.
Storage of data in internal memory.
Detection and quantification of more than 12 substances (Default).
Working principle Ion Mobility Spectrometry (IMS)
