Chlorodimethylether (CMME) and Bis Chloromethyl-ether (BCME) as well as Ethylene dichloride (EDC) and Methylene chloride (DCM) are well known as carcinogenic substances, like other chlorinated hydrocarbons. BCME is also very toxic. These particular chemicals are widely used in the world of chemical industry, especially in the production process for ion exchange resins. CMME in that case acts as a precursor for those resins while BCME is generated as an impurity which cannot be avoided.


A potential exposition to human bodies can occur by inhalation as well as by resorption processes through the human skin. Humans exposed to chemicals like this, normally are workers in chemical plants, where ion exchange resins and similar products (polymers) are fabricated. So it is mandatory to monitor work places in terms of BCME/ CMME/ EDC/ Methylene chloride detection at an early level to avoid worker’s exposition to these compounds.


IUT Technologies IMS-Analyzer is capable of detecting and quantifying substances like these in the required ppb concentration level. The coupling of a gas chromatographic preseparation prior to the high sensitive IMS technology provides an analyzing performance, where each of the named compounds can be measured and quantified separately with outstanding sensitivity, repeatability within cycle times of minutes. by applying GC-preseparation, the unique method properties of IMS are available even in the background matrix of chemical production plants.

IMS-Analyzers are based on a fieldproven Ion Mobility Spectrometry (IMS) technique that is highly selective and sensitive to chlorinated hydrocarbons. IMS is an atmospheric pressure, time of flight detection technique. The sensitivity, selectivity, and speed of response make the technique superior in many aspects compared to other monitoring methods. The industry-proof spectrometer design allows using these advantages in 24/7 stand-alone operation. Unlike electrochemical devices, the IMS units are impervious to extreme temperature or humidity conditions. IUT Technologies IMS units are designed for long term, continuous measurements with little or no maintenance and no consumables. The electronics are completely solidstate without moving parts or optics to require alignment.
