Introduction: PFIB (Perfluorisobutlyene) is a gaseous compound from the group of Fluorinated Hydrocarbons. It is very toxic at ppb- concentrations already, inodorous, colorless, flavorless, heavier than air and very stable. The effects of intoxication can occur hours or even days after exposition. Thus, it is very dangerous. In specific processes in the chemical industry this compound is produced as un- wanted by product, such as the production of PTFE (Teflon), which cannot be avoided. Since there’s no ...

Introduction: 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 ...

Airborne Molecular Contamination (AMC) is a general term for existing molecular contaminations in clean room environments. These compounds belong to very different groups with very different mechanisms of damage. AMC is a concern for any high technology manufacturing process, especially in the microelectronic industry and is getting more and more in the focus of interest. AM-contaminations may cause adverse effects on production tools and consequently increase costs for high-tech companies. These airborne ...

Introduction: DMS (Dimethylsulfate) is a liquid compound with a high vapor pressure. It is a widely used basic chemical in the production of Agrochemicals, Cosmetics and Pharmaceutics. It is very toxic at ppb- concentrations already, but also carcinogenic and mutagenic. Furthermore by hydrolysis sulfuric acid is formed, so it is very corrosive also. Since there’s no warning effect in terms of irritation and/ or odor, dangerous amounts can be incorporated without realizing. The effects of intoxication, which ...

Introduction: Phosgene is the common name for Carbonic Dichloride, a gaseous compound. It is very toxic at ppb- concentrations already. Phosgene is a very important precursor in the chemical industry for the production of e.g. polyurethanes, pharmaceutics colors, etc. and therefore widely used. Even though it is handled in hermetic closed systems only, several generators for Phosgene are in operation worldwide to at least avoid all risks caused by transportation also. The effects of intoxication can occur hours or ...

Introduction: TCP (1,2,3- Trichloropropane) and DCP (2,3- Dichloropene) are liquid compounds from the group of Chlorinated Hydrocarbons, defined as carcinogenic and mutagenic at low concentrations already. Due to the pretty high vapor pressure of these liquids, a significant health- risk is created by handling. TCP and DCP are widely used as chemical precursors in production processes for the synthesis of various products, such as chlorinated solvents and Agrochemicals. Furthermore DCP is also used as a ...

Introduction: Hydrazine is an inorganic compound consisting of just Hydrogen and Nitrogen. It is a clear and oily liquid with a high vapor pressure. Hydrazine is very reactive and very toxic, even at low ppb- levels already. It is carcinogenic, irritant at mucous membranes and damages lungs, the nervous system, kidneys and the liver. Hydrazine is used for various technical and chemical purposes such as a corrosion inhibitor in tubes and containers, in chemical production processes as reducing agent or Hydrogen ...

The Aspec Mass Spectrometer system is ideal for interfacing with most Thermal Gravimetric Analysers. By connecting the specially designed, heated Mass Spectrometer sample Inlet probe, evolved gases from a heated sample within the TGA reactor can be measured and recorded with respect to time. In addition, both the temperature ramp (profile) and weight loss signals from the TGA can be integrated directly into the Mass Spectrometer software. It is ...
