The Fumi-Analyzer is a mobile multi-gas/multi-sensor detector developed at IUT/IUT Medical for the high-sensitive detection of toxic fumigation gases. This new device has been developed taking into consideration the experiences and requirements of our customers. Herewith fumigation and other toxic gases can be detected and identified within the required concentration range without any enrichment directly at the container. Due to the sensor extension the Fumi-Analyzer can identify, beside other gases, also fumigation gases like Sulfuryl difluoride (SO₂F₂) and Formaldehyde (CH₂O). Therefore it is the first mobile device able to detect and identify all relevant fumigation gases with the needed sensitivities. Beside the fumigation gases, also other toxic gases (industrial gases) which are released from the transported goods create a risk.

The CWA-Analyzer is a multi-gas analyzer for the high-sensitive detection and identification of Chemical Warfare Agents (CWA) and/or Toxic Industrial Chemicals (TIC) developed by IUT/IUT Medical over more than 20 years. It is best suitable for the use in homeland security, building protection, and CBRNE application in general. It is an Ion Mobility Spectrometer (IMS) (also as GC-IMS) with high sensitivity in the lower ppb-range and with high resolution. It is also be available as GC-IMS, gas chromatographic (GC) column coupled with an IMS to enhance the selectivity and to reduce cross sensitivities available with still high sensitivity for extreme requirements.

The IMS-Analyzer is a multi-gas analyzer as Ion Mobility Spectrometer (IMS) with high  sensitivity in the lower ppb-range and high resolution. With this trace-gas analyzer toxic gases can be detected and identified without any enrichment directly in situ already at a very low concentration level. For the further enhancement of the selectivity and further reduction of cross sensitivities the IMSAnalyzer is also available as GC-IMS approach. There the IMS is coupled with a gas chromatographic column (GC) for pre-separation.

The PID-Analyzer is a multi-gas analyzer as gas-chromatograph (GC) with a Photo Ionization Detector (PID) for the read-out able to identify compounds. It has a high sensitive detection and identification of Volatile Organic Compounds such as Benzene, Toluene, Ethyl benzene and Xylene (BTEX). The PID-Analyzer does not show any interference (quenching) from humidity and offers manual and automatic analysis. With this detector combination the disadvantage of conventional PIDs is overcome and therefore allows the identification of compounds. The PID-cell used in this system is a special designed PID with sensitivity in the ppb-range. Since no carrier gas is required the operational costs of the PID-Analyzer (GC-PID) are low.

Permeation (lat.: permeare = percolate, penetrate) describes the process of penetration of a substance through a solid material, driven by the force of a chemical potential gradient like a pressure or a concentration difference. Without any external influence the substance which permeates, moves always into the direction of the lower concentration.  By using a tube made from any polymer like PP, PTFE, PE, filled with a liquid or gaseous substance the wall of the tube acts as the solid material, the membrane, which is penetrated. Since one can imagine this as a penetration molecule by molecule, the process is very stable, reproducible and can be controlled with an extremely high precision just by varying a small amount of parameters.

Certain gas detection applications are better served if the sample is diluted before it reaches the analyzer. Sample dilution is used to: measure beyond the nominal range of the analyzer, extend the dynamic range.

Our MPS (Multipointsampler) is designed for subsequently continuous monitoring of multiple measuring points. It’s designed to work as an integral part of a measuring system. It is used for online measurements. The sample pump, valves and sample lines are at ambient  temperature. It is an ideal tool to measure components in ambient conditions from several measuring points.
